Hello,

I try to run dovecot 1.0.3 on RHEL 5.1 beta.

As soon as I start it I get the following output and it's impossible to IMAP-log in over network.

I've been following the list for a while and it seems to ring a bell about setting the correct ulimit, but I can't find the thread anymore, so I need to ask. :(

Here's the debug output I've put together. I've been not able to core dump dovecot as described in the debug docs:
