Hi, I see a lot of crashes in my syslog lately. Specifically a sequence of errors exactly like this (only the timestamp differs). > Nov 10 21:29:53 khitomer dovecot: imap-login: Login: user=<user@hostname>, > method=PLAIN, rip=XXXX, lip=YYYY, mpid=ZZZZ, TLS, session=<TTTT> > Nov 10 21:29:53 khitomer dovecot: imap(user@hostname): Panic: file > mail-storage.c: line 2222 (mailbox_copy): assertion failed: (!ctx->unfinished) > Nov 10 21:29:53 khitomer dovecot: imap(user@hostname): Fatal: master: > service(imap): child 35108 killed with signal 6 (core not dumped)
I have the mail storage on ZFS, one separate filesystem per user and
another for the lucene indexes. I.e. these are separate ZFS filesystems
(not pools):
> /var/mail/vhosts/%d/%n
> /var/mail/vhosts/%d/%n/lucene-indexes
Any idea what could be going wrong?
