messages causes major troubles on this box - more than 500 MB of virtual memory allocated to the "imap" process is quite a lot and often causes random processes to fall victim to the OOM killer. Probably easier if you just try if beta3 has fixed this already, so we don't waste time for nothing :)
Ok, I just installed and tested beta3. The occassional "hang" of the connection I experienced with the ancient "stable" release seems to be gone now.
However, deleting (marking as deleted) large batches of messages still requires lots of RAM:
28507 gunter 17 0 211m 30m 8572 R 82.9 50.5 6:45.00 imap
After the operation finishes, dovecot remains at a VIRT size of 209m.
This look pretty much for me, even for deleting 7000 messages in a row.
This machine has 64m of physical RAM and runs the 2.4.27 Linux kernel from Debian Sarge.
I've not tried yet if the memory utilization additionally doubles on the second try if dovecot got OOM killed on the first - I added sufficient swap space before the test - but I could do if this would be interesting and/or helpful for you.
Greetings,
Gunter
