User-Agent: Opera/9.02 (Windows NT 5.1; U; en) Build Identifier: version 184.108.40.206 (20061207) Summary: Thunderbird process becomes unresponsive after selecting a large quantity (1000+) messages and hitting shift+delete. A check of the Task Manager shows memory usage heading towards 1000MB of RAM and growing. Suggest looking at last post of bug: https://bugzilla.mozilla.org/show_bug.cgi?id=47645 Would be good to implement some magic and then small batching of delete requests (may be 100 at a time). I'm sure the problem here is client side as there is very little IMAP traffic. Looks like the problem is all about updating client side caches. Reproducible: Always Steps to Reproduce: Reproduce: Find a folder with 1000+ messages. Select All Shift+Delete Actual Results: Visually, nothing happens - the program (and all of windows) becomes unresponsive. Memory continues to rise until program killed. Expected Results: Ideally, the messages should instantly disappear (however fast the background imap delete takes). Used against a Dovecot server using Maildir. Quite a powerful server that was reporting loads of <1.00 during the time that thunderbird was frozen.
ref bug 218075, bug 296453 I recall seeing commentary from david somewhere on this, but maybe that was about copy/move, or marking junk?

Daniel, could you please check the issue still occurs in the latest supported Thunderbird 2.0.0.x or trunk nightlies?
Whiteboard: CLOSEME 2008-04-30
Using 220.127.116.11 Well I don't have a folder with 1000+messages at the moment but just tried with 400+ messages and after about 20 seconds they all disappeared. Memory rose from 200k - 245k (and stayed there after the delete) but I'm not seeing my >1GB memory usage as I did before. Possibly exponential rise in memory though so someone still needs to try with 1000+ messages.
Daniel, thanks for checking. Are your figure MB or K? Anyway, Your results consistent with mine, so closing WFM... tested version 3.0a1pre (2008041203) - core duo laptop, wireless G, connected to cable modem (my slowest connection) - imap account settings - delete="move to trash", use idle, cache connections=5 - folder sort=threaded - folder "lotsamsgs" is 23,478 messages, 91MB WS WS cpu WS peak private after startup :03 30140k 31276k 15612k mouseover lotsamsgs 47MB remove mouseover 36MB after clicking fld :10 52460 52640 35960 select all :13 52436 52764 35932 shift+del :33 58584 67896 43048 ~20sec wall clock net change from delete - 6MB HOWEVER, note this odd aspect of the results: - after shift+del is done, folder stats show 7 remain but thread pane is empty - leave folder and return to lotsamsgs, the subjects of the remaining msgs appear - nothing unusual about these msgs that didn't get deleted, afaict
