(Archived) Evernote 2.0.5 churning cpu

werdna · March 7, 2011

I have recently upgraded to 2.0.5 and I see that evernote is now eating away at my cpu. When my machine is otherwise idle, Evernote is using 65-70% of the cpu. Also, when trying to use evernote, it is almost unresponsive. It takes about 1 second for each character to appear when I type.

Any ideas what might be happening?

I took a sample of the evernote process using the activity monitor. I tried to upload, but your bulletin board does not accept .txt files. I changed the extension to .jpg. You must change the extension to .txt to read.

I think that your EN database is starting to rival archive.org.

Isn't that the point?

Thanks for the feedback, but our Mac and Android clients don't share a single line of code, so the behavior is a coincidence (if it is actually Evernote in both cases).

Bandikoto · March 25, 2011

I was seeing the same CPU-chewing behaviour on my mac (10.6.5) with Evernote 2.0.5 as well today. Downloading the Prerelease version has not fixed this. I'd be happy to supply whatever information you wish to help track this down. EN's CPU is currently sitting at 97.7%, which is generating a lot of heat and thus fan noise.

Yesterday, after firing up Evernote (2.6.1) on an Android device, something started hammering the CPU and making the device hot to the touch. Power-cycling the device in the middle of the lecture didn't change the heat problem - the device running out of battery and shutting itself off did. After charging it overnight, it is behaving properly.

I'm thinking that (a) your version numbers aren't synchronized (there lies madness) and ( you definitely have a cross-platform bug. Both the mac and the android are displaying the same CPU-pegging behaviour.

If it's still doing that tomorrow, try contacting Support.

Hi,

I'm suffering through the churning cpu issue since upgrading. I've left Evernote 2.0.5 running for about 6-7 hours now. Still churning away. Should I install the pre-release mentioned in this thread or open a support ticket?

engberg · March 15, 2011

Our Mac team took a look at one of the samples provided, and it looks like the client was busy generating new "thumbnails" for each of the notes in your account. Whenever we release a new version (like 2.0.5) that includes changes to the thumbnail rendering code, the client will need to go back and retroactively render your thumbnails again. This is a one-time operation for that version, so the CPU should go away after an hour or two.

werdna · March 15, 2011

I received the same message from evernote support and I downloaded the pre-release version. Now, I am seeing that the problem has gone away. Thanks everyone for your help!

That-Dude · March 15, 2011

I have been in contact now with support and been given access to a pre-release version. I had to uninstall the current version in a specific way an install the new version in a specific way. After that the problem was gone.

This was their message, which I hope is ok to post here:

We believe that the latest Mac pre-release version may address the issue that you reported. Please accomplish the following:
Quit Evernote from the elephant icon in the Menu Bar
Drag the Evernote application to the system Trash
Reboot your Mac
Download and install this pre-release version of the Mac client:
http://www.evernote.com/about/download/ ... releaseMac
When you open our .dmg, make sure to drag the Evernote icon into the Applications folder instead of running it from within the installer package.
Eject the disk image and delete the installer file before you run Evernote.
Let us know how this works for you.
Thanks,
****

In general, if the Mac client is using a lot of CPU and becoming unresponsive for long spans of time (e.g. 10 seconds+) with the "beach ball" icon, then it's worth trying a reboot and possibly a reinstall first.

If the problem persists, we'd like to track down a bit more information via the Activity Monitor. You can select our application there when the app is "hung" and press the "Sample Process" button to get a snapshot of what the app is doing at that time. If you do this on a couple of different occasions, we can collect even more results.

If you provide these to Support via an inquiry, we can pass them along to engineering for analysis.

Thanks

werdna · March 14, 2011

Thanks, JMUnderwood11. These are some good hints. I did try "uninstalling" (ie- deleteing evernote.app) and reinstalling, but I didn't go into the detail that you describe.

JMichaelTest · March 13, 2011

I too have that problem with version 2.0.5..
CPU on a macbook pro is at 95-100% and the notebook is getting hot as hell of course. Not to speak of the battery running out very quickly.
I can't keep using EN under these circumstances, although I would really like to.
Rebooting or quitting and restarting the app didn't help of course.
Also the CPU is at these high value perpetually. It's not like it stops after 5 minutes or even 5 hours. It just goes on. . .

First, I agree that anyone who is consistently experiencing very high CPU usage with ONLY Evernote running should file a Evernote support ticket.

Having said that, there are few things worthy of note:

[*:2g6s7r56]This issue could be localized to your computer
- [*:2g6s7r56]I'm running EN Mac 2.0.5 (130391) without any problems
  [*:2g6s7r56]I just did a massive Tag reoranization that probably affected about 1,000 Notes
  [*:2g6s7r56]I made all the changes on EN Win 4
  [*:2g6s7r56]When I did the sync on my MacBook Air (1.6 Ghz CPU, 4 GB RAM) it took only about 20 seconds, with the CPU peaking at about 40%
  [*:2g6s7r56]I have never experienced any performance issues with EN Mac

[*:2g6s7r56]The fact that you guys are having this very high CPU usage suggests that there may be something corrupt on your Mac, either data, software, or both.

[*:2g6s7r56]Unless you have a huge number of Notes (like well over 10,000), you might want to try an Uninstall / Reinstall of EN Mac, after making a backup of your Mac

[*:2g6s7r56]Make sure you do a backup first
[*:2g6s7r56]See the following articles for recommended uninstall procedure:
- [*:2g6s7r56]MacRumors.com:

Uninstalling Applications in Mac OS X
[*:2g6s7r56]MacWorld.com: Mac utilities: Do uninstallers work?

[*:2g6s7r56]Make sure all of the Evernote folders have been deleted or cleared.

Good luck, and let us know what the was the final solution.

For such a clearly serious issue I think your best course of action is to open a support case.

Sorry to reign in on the fun, but the cpu churning is continuing to happen for me. It is so bad that my system becomes unresponsive when evernote is on and typing when inside evernote is horrendously slow. It takes ~1 second for each character to appear. I have left evernote running for a few hours just to see if the cou would eventually go down (it didn't).

I pasted a sample of the process over at pastebin:

http://pastebin.com/827SXrxA

At this point, evernote is unusable, and when it is running, it is making my system unusable. Perhaps I should downgrade...

BurgersNFries · March 10, 2011

FWIW, the articles you've posted in the past always are interesting to me & normally end up getting stored in my EN database.

Raymond Chen is a god of Windows programming; his blog is on my daily reading list.

It's not all germane to the situation, though. If the 100% utilization goes on for hours, then there may be something going on, even if the application has lost responsiveness: I don't think that Evernote has spun off a thread calculating digits of pi, for example. And if you're running on battery power, it's probably not a great situation, either. Truthfully, this situation is kind of difficult to diagnose from afar; there must be tools available on the Mac that can help pinpoint the busy thread (on Windows I'd be reaching for Process Explorer).

BurgersNFries · March 10, 2011

ZOMG! This program is using 100% CPU!1! Think of the puppies!!11!!1!1!eleven

Good read, Jeff! (And funny analogy!)

Metrodon · March 10, 2011

It just looks like the sync process got it's knickers in a twist and a simple restart fixed the problem.

A CPU at 100% is not in and of itself necessarily a problem, so long as the rest of your system remains responsive. If the program is performing a computationally intensive algorithm, but yields to other processes, then there should be no problem. If your system *does* lose responsiveness, then that's when you should worry.

I don't think I agree with that. Spiking at 100% is one thing, but if it continues at 100% for a sustained period, say over 1 minute, then this could be cause for concern for most applications.

If the same app continues to show this behavior over several hours, then I would be concerned unless you can easily explain it by what the app is doing. Re-downloading your entire EN account might generate some high CPU usage if you have lots of notes, but I would still be surprised [f it had a sustained level of 100%.

came back to my computer this morning to find Evernote 2.0.5 hovering close to 100% CPU, though the app is still responsive; a sample is below; there was nothing relevant in the logs, but when i quit the app, i got the message "are you sure you want to quit ... currently syncing ..."; when i restarted Evernote the cpu usage was normal

Of course doing a reboot as you did is one of the first things to try. If it continues to run at a very high % then either you have a poorly written app, corrupt data, and/or corrupt app.

Scratch that...the problem seems to have fixed itself. A single reboot did not work, but after a second one the problem seems to have gone away. Thanks for your help!

Odd...I guess the attachment never made it. I'll create another sample and put it into a reply.
