[Dovecot] Panic in Dovecot 1.1.3: index-mail.c: line 1091: assertion failed: (!mail->data.destroying_stream)

[Peter Eriksson]

Dovecot 1.1.3
Solaris 10
SPARC (Sun Fire T1000)
Compiled with Sun Studio 12 compilers.
Maildir on NFS
Indexes on local disk (UFS).
'dovecot -n' output attached.


IMAP process crashes for certain (many, but not all) users when
accessing certain folders (in the example below, in crashes when
accessing my INBOX, about 1700 mails). I could access other
mailboxes without problems. And a simple telnet to the imap port
followed by a login works fine.

Erased the coredumps (was filling up the system too quickly) so I
can't really produce a backtrace right now (had to back down to 1.0.13
again even though that one has another core-dump-generating problem -
but that is atleast limited to only one specific user so far). Going
to set up a separate test server to test things more without disturbing
our normal operations...


I started with an empty INDEX directory to make sure there weren't
problems with old corrupted indexes.
