Hi Timo, I've got a crash with dovecot 2.2
dovecot --version 2.2.rc2 (69c26a9e3be5)
It's occured when accessing with imap on a large mailbox (around 50k messages)
imap(clean-quarantine@spamguard.fr): Panic: Buffer full (4254 > 4248, pool <none>) These should fix it: http://hg.dovecot.org/dovecot-2.2/rev/689dbeadf168 http://hg.dovecot.org/dovecot-2.2/rev/ee7352f46d1e
Thx Timo It's ok now
