[Dovecot] IMAP error with squirrelmail - how to debug?
When moving messages with squirrelmail (or kmail), I get the following error:
ERROR : Could not complete request. Query: COPY 3 "INBOX" Reason Given: Unexpected EOF
According to the config I switched on rawlog:
# This would write rawlogs into ~/dovecot.rawlog/ directory: mail_executable = /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap
rawlog.c was altered in order to have /tmp as HOME. But I see no logfiles being generated.
Environment: lastest dovecot from CVS, vpopmail and local users (error with both types).
Another issue:
Ocassionally the auth process dies:
Feb 26 21:08:49 servername dovecot: child 28641 (auth) killed with signal 11

Ok, I've found the reason for this. Setting
maildir_copy_with_hardlinks = yes
cures the problem. Nevertheless I think the original problem is worth debugging. I'll provide the necessary debugging information, if someone is interested and tells me what to do.

While it's worth debugging, there's usually little reason to not use hardlinks, and the performance gain with large messages is astounding. For those who aren't familiar with hardlinks, when messages are moved from one folder to another via an IMAP command, I believe they are copied/deleted instead of moved. If hardlinks aren't used, the message must be replicated, then the original deleted, which on a large server with large messages, could significantly increase I/O. With hardlinks, a link is created, and the original link removed. Very little I/O.

Have you checked whether your file system is full?
Nevertheless I think the original problem is worth debugging.
An strace of the imap process will likely reveal the cause.
