[Dovecot] Panic: file mempool-system.c: line 104

[Martins Lazdans]

Ok, I unblocked that IP and started Dovecot with
`ulimit -c unlimited && /usr/local/sbin/dovecot`
and will see if that IP will return.

But I totally forgot I am using Google`s perf-tools
(http://code.google.com/p/google-perftools/) tcmalloc library. Maybe
that library is faulty and/or incompatible with Dovecot?

export LD_PRELOAD=/usr/local/lib/libtcmalloc.so

However, I switched to Google`s libtcmalloc.so long time ago, and
dovecot was running just fine until today. MySQL, nginx, clamav and
postfix are running fine too.

P.S.
I got 2 responses from you :)
