We upgraded from Dovecot 1.0.15 to 1.2.5 last night, on Solaris 10 using
mboxes, mostly without issues.
However I had to trash the index/cache files (too many folders were
showing corruption issues which is especially bad for Prayer Webmail
".prayer" folders that store preferences; Prayer sees a disconnection as
the folder being missing!).
I've had one imap process panic in mailbox sync (as I mentioned above,
the index files have been newly created in 1.2.5):
> Sep 30 09:57:10 imap-login: Info: Login: user=<xxxxxxxx>, method=PLAIN, rip=134.225.xx.xx, lip=134.225.16.6
> Sep 30 09:57:10 imap-login: Info: Login: user=<xxxxxxxx>, method=PLAIN, rip=134.225.xx.xx, lip=134.225.16.6

> Sep 30 09:57:11 dovecot: Error: child 25384 (imap) killed with signal 6 (core dumped)
This looks like it was the user's first connection since the upgrade, as
well. Here's the backtrace:

I'm also seeing some other errors, e.g. :
> Sep 30 10:37:06 auth(default): Error: Master request 15820.607 not found
> Sep 30 10:51:27 dovecot: Error: child 29959 (login) killed with signal 11 (core not dumped) (latest ip=134.225.1.46)

> Sep 30 10:54:03 imap-login: Warning: Error sending handshake to auth server: Transport endpoint is not connected
How do I get the login (presumably imap-login) processes to dump core
(or do I need to insert gdbhelper)?
Dovecot -n output (%J is a local hash function and we don't use the lda;
my start-up script sets the fd limit to 4096 once Dovecot has started):
> # 1.2.5: /opt/RDGdovect/etc/dovecot.conf
> Warning: fd limit 2048 is lower than what Dovecot can use under full load (more than 4352). Either grow the limit or change login_max_processes_count and max_mail_processes settings
