I selected an email inbox that had 30,000 unread messages. I marked the folder 'read'.

Thunderbird memory proceeded to go through the roof. It got to 1.5GB (that is a 'G') of memory used.

At the end of the operation it did go down (slowly) to a more reasonable level (took a long while to come down).

Also, I often have to restart thunderbird because its memory usage exceeds 250MB. If its not a memory leak then for sure it not reclaiming its memory.

Reproducible: Always

It actually took over 20 minutes to come back from the effort.

with that many messages a large amount of mem will be used. What version of TB are you using, did you create a new profile?

sounds familiar but I can't put my finger on the bug.  When you say marked it read, did you do ctrl+shift+c?  Or did you select all the messages and do "M" or mark as read?

I selected the folder and right clicked on it and selected the option 'Mark Folder Read'.

I'm running TB under Win/XP with all the latest service packs and patches.

My TB version: (20081209)
Version: unspecified → 2.0
David Marcus  - imap folder, or local folder?

David, can you reproduce this with version 2?
if you are ready to use version 3 and haven't yet that would be a useful test.
suggest using build with latest patches at
backup your profile before using v3

please also indicate what version and name of mail server
