cryus-imap-2.2.12 crash on freebsd 6.0

[Adrian Florin Teodor]

Hello,

I have cryus-imap 2.2.12 running on a freebsd-6.0 box, after a
spam attack, reading emails for two users doest work.

When i try to read my email cyrus-imap exists with
following errors:

Jun  8 12:53:05 host master[462]: process 68243 exited, signaled to
death by 6
Jun  8 12:53:05 host master[462]: service imaps pid 68243 in BUSY state:
terminated abnormally

I tried to reconstruct the user mailbox, but doesnt fix the problem.
I'm new to cyrus-imap, so if any of you has any ideas
how i can fix this, thanks in advance.

Adrian.
