[Dovecot] imap core dumping on signal 10

Wed Jul 21 01:53:52 EEST 2010
We are just trying to bring up a new server and chose to use Dovecot
rather than the uw-imap from our previous servers. At this point I am
just testing with some throw away accounts using squirrelmail. I can
load my inbox, but then the imap connection is lost. I presume you need
some real information to get your teeth into, so this is going to get a
little long. I'll give you three things below:
1. a piece of /var/adm/dovecot.log,
2. the output of `dovecot -n`, and then
3. the full gdb trace back on the core file.
I'm hoping that, aside from there being a bug that causes core dumps, we
might have a straightforward misconfiguration that we could fix and have
a working installation.
All info at end.
