1171468 - After deleting 2k messages UI is locked, progress bar is active, no indication of what is happening. 100% processor for more than 20 minutes

Status: RESOLVED DUPLICATE of bug 693659

(Thunderbird :: Mail Window Front End, defect)

Description

[ultimitloozer]

Attachment: wtf is it doing?

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:38.0) Gecko/20100101 Firefox/38.0
Build ID: 20150525141253

Steps to reproduce:

Deleted approx 2000 emails from an IMAP account.


Actual results:

Emails eventually deleted, but Thunderbird still consuming approx 25% of all CPU cycles, progress bar behaving flaky (doesn't show consistent progress, goes up and down at times, but does not appear to advance beyond the 50% mark), entire interface becomes unresponsive up to 40 seconds at a time, and there is no indication of what it thinks it is doing.  This after more than 1 hour post-deletion.


Expected results:

At least provide a means for a user to see what Thunderbird *thinks* it is doing.  With MS Outlook 2007, a user can click on the status bar to get a dialog indicating EXACTLY what Outlook is trying to do (logging into server, downloading headers, downloading messages, compacting files, etc).  It is directly tied to the progress bar.  Your one-line status bar *sometimes* flashes a message about what it is trying to do, but provides 0 details and does not seem to be associated with the progress bar.

Keep the primary UI thread separate from all others so it does not become unresponsive during long-running tasks.

If it is still happening what shows in tools, activity manager?

First of 2 screenshots of Activity Monitor (since I can't just dump it to a text file).

Forgot to add: I have no clue where the extra 3000 "deleted" items came from.  I only selected and deleted just over 2K items.  Everything else appears to be in the mailbox still, so it isn't like I am missing 3K+ messages.

so starting at about 6:21, when activity manager shows 5489 messages deleted, it was unresponsive multiple times for up to 40 seconds.

Yes.  Trying to do anything in the UI - select a message to read, deleting individual read message, scroll message headers, click on the menu button, etc. - would result in the UI freezing anywhere from 10 to 40 seconds and end up with Windows popping its nice little "(Not Responding)" message into the title bar.

The Thunderbird.exe process was consuming 25% of my CPU cycles (1 entire core - #3 - of my quad-core processor) the entire time from the initial deletion until I shut down my system about 5 hours after that deletion to add another hard drive to the system.

I have not yet deleted any other messages and won't until the remainder of my work is done for the day.  I don't want to keep restarting my machine in order to restore processing balance in the system since I don't believe that a background task should ever be consuming that many cycles for that much time.

System originally built about 4 years ago but undergoing infrequent hardware & frequent software upgrades.  There have been no hardware upgrades since the last complete bare metal reinstall about 20 months ago.  It is overdue for a complete rebuild but it does not explain this type of behavior, including the later loss of the contents of one of my email accounts on the system and the length of time (measured in days - 4 so far and still not done) it takes to rebuild the mailbox on the system.
