Build Identifier: Thunderbird version 0.6 (20040502)

After a period of inactivity (several hours) Thunderbird becomes completely

This is completely reproducable for me with v0.6, while v0.5 did not have this

Reproducible: Always
Steps to Reproduce:
Open Thunderbird and wait.

Actual Results:  
Freeze requiring kill.

Expected Results:  

I would like to help track this down.

This bug causes dataloss in some cases.

After returning from a period of inactivity, in some cases Thunderbird appears
to be responsive. So I compose an email -- only to have Thunderbird hang upon
pressing "send."

How can I dump a long or some such to help track this down?

PS: Sorry for the dupe.

can anyone try a trunk nightly to see if this problem still exists there?

I also have the same bug in Mac OSX. After computer sleep and rewake or unactivity it hangs. I never 
had this in previous versions, only 0.6

I find this on Mac OS X 10.3 with a Thunderbird 0.7.1 20040702 nightly, and I've
noticed it since 0.7.0. It seems to occur after a variable amount of time,
anything from ten minutes upwards. The symptoms are much as those reported
originally; I get the OS X 'beachball' busy cursor, OS X decides the program
isn't responding, and it has to be killed. I haven't tried a trunk build yet,
but I may later today.

Think it is related: my windows build tends to consume 99% cpu load after a
period of time. Only checked mail and send one.
Will try to reproduce and look if it is allocating more memory/gdi object etc.

This might be related.

I don't use the nightlies, but this has been going on at least since 1.0.  I'm
on Windows XP.

I've never had the crash, but Thunderbird is horribly slow to do anything (view
a message, write a message, change folder, pull up a menu, anything) after a
long time of inactivity.  At it's worst, over a minute before anyhting works the
way it should.

At first I thought it was just after the screen saver had been in use, but it
happens if Thunderbird has been sitting in the background while I'm doing other
stuff.  I don't minimize, if that's relevant.  I can't figure out what the time
threshold is before this starts happening.

It's a big show-stopper at the moment.
My boss went back to OE because of this.

Ways to reproduce:
Keep Thunderbird open all day with (multiple?) IMAP accounts (I have 2 IMAP

At the end of the day my CPU load is all consumed by Thunderbird (99% cpu load).
GDI objects are not climbing (much) and steady at 270 objects.
Memory usage is around 35.268K (not rising).
A "netstat -a -n -o" in dos-box shows me 9 IMAP ESTABLISHED connections and 1
CLOSE WAIT connection to my IMAP servers.

No Javascript errors are warnings are show ATM.

I hope this bug gets fixed soon, will be glad to perform other additional tests
on request.

My build is  WinXP (20050418)

could this be related to bug #293568 maybe?

What kind of imap server are you using? If it's a courier server, have you tried
setting the max number of connections to 4, in the advanced imap server settings?

I experience the same problem with Thunderbird version 1.0.6 (20050716).  I am 
forced to close the application and wait for it to unload.  Upon restart of 
the program, it seems to work.  It occurs with an inactivity period of a 
couple of hours.  My operating system is Windows xp professional.  my email 
account is

I get this too, have had it ever since I started using 1.5a1.

After a while Thunderbird just hangs.

I've got 2 IMAP accounts, one connects to a Surgemail server (
and the other to Courier IMAP.

I don't have this problem on another machine running 1.07

It is still happening in 1.5b2.

Still happening in 1.5rc1 on my WinXP machine... also installed on my Apple Powerbook, and it now happens there too. Also know someone else who's having the same issue on a Powerbook.

I can confirm this with 1.5RC1 under Windows XP SP2. After a period of inactivity of no more than 1 hour I have to force-kill Thunderbird.

Running IMAP/SSL with approximately 12 subscribed folders.

This bug has been a major PITA ever since I started using TB 1.5b1, and it hasn't gotten better with 1.5rc1 or the 1.5rc2 test build (20051201), and in my case I suspect it's IMAP related. I'm using Cyrus IMAP via SSL, on WinXP.

Typically I see this bug when the computer is waking up from standby mode. Sometimes TB will wake up right away, but sometimes the window won't even get redrawn for 5-10 minutes, and often it won't get redrawn at all, so that I have to use the task manager to kill TB. This freezing-up happens almost daily.

Possibly related: TB just now froze up on me when it was trying to auto-save a draft during compose. Just by chance, I had momentarily lost my Internet connection (ADSL), and TB tried to auto-save the draft during this time. Apparently due to the lack of IMAP connection, TB completely froze up: the status bar says "copying message to Saved folder" (Saved = my Drafts), the cursor is frozen into hour-glass mode in the compose window, and if I try to switch back to the main TB window it doesn't get redrawn at all. I waited about 20 minutes just to see if TB would snap out of its petrified state, but no luck.
This doesn't appear to be a problem under 1.5 RC1 or 1.5 RC2 when using Dovecot as the IMAP4 server.  I've been using RC1 here since it was released, with no problems.

Just had 'this' occur to me.
At the time, it seemed to be updating the various MSF files for the local copy of the folders held on the IMAP server. The file-sizes were changing by a few bytes, nothing more. Maybe garbage collection of some sort?
I'm using 1.5. I have only a single account (IMAP) set, and a bunch of local folders held elsewhere. Close and restart Thunderbird, and all is well.

I've had this happen a lot - when I break into the debugger, nothing interesting is going on.

I'm experiencing the same problem after only a few minutes. I've got several IMAP accounts on the same Courier IMAP server, plus a couple of POP accounts.

The Courier IMAP server accepts up to 32 connections. Thunderbird 1.07 worked reasonably well, although it did see this problem from time to time. In particular when connected to the Internet over dialup.

Ever since switching to Thunderbird 1.5 the problem has gotten so bad that I'll have to downgrade to 1.07.

I'm seeing this as well.  I'm running TB version 1.0.7 (20050923) on WinXP.

Typically, I'll hibernate my laptop when leaving work, open it later in the evening, hibernate it again, etc.  This works fine for a while, but eventually TB will start eating the CPU.  Also -- and this is probably important -- TB is doing a ridiculous number of "other I/O" (tens or hundreds of thousands per second, with the total count in the hundreds of millions).

I've also seen this sort of behavior with Firefox.

I have been running version 2 beta 1 for 24 hours without any problem. In particular it seems that this bug has disappeared.
