[Dovecot] RHEL 5.1 beta, Dovecot 1.0.3: error while loading shared libraries?

[Patrick Ben Koetter]

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:
