User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.115 Safari/537.36

Steps to reproduce:

Opened Thunderbird. Used it for a while. Let it sit for a while.

This is happening for multiple users in our environment on RHEL 7.2 using Thunderbird 52.0.1 and 52.2.1. I've rolled a couple users back to 38.5.0 (packaged/distributed by Red Hat) and they are not experiencing this issue.

The users home directories (and thus, their Thunderbird profiles) live on network storage accessed via NFS.

The issue persists with a fresh profile.


Actual results:

Thunderbird eventually starts to peg one CPU core to 100%. The UI becomes sluggish, clicking on new messages take 1-2 seconds to appear in the viewing window. Typing into the compose window will hitch and lag.


Expected results:

Thunderbird UI should remain responsive to user input.

<predictably, another linux user reporting performance issue><nothing against linux users>

Hi Frank. You cite using nfs. We know there are performance issues with NFS. Can you reproduce this if the profile is on local disk and not nsf?

There may be other issues, but lets start with that.

I moved a test user's profile off of NFS to local storage on Friday. The problem still persists today with a thread pegging a core to 100% cpu.

Was there also an issue with version 45, or had you skipped over it?
In the run up to high CPU, do you see anything in Thunderbird's Activity Manager or Error Console?
Any Thunderbird addons installed?
And desktop environment?
Please attach to bug report a screen shot of the Thunderbird UI - specifically we are looking for any activity in status bar bottom of screen.
