Just to bring a conclusion to this topic, the problem is actually bad memory.
On the same machine a Postfix daemon has just died, checking the logs:
May 28 08:58:31 friends postfix/master[2933]: ess
May 28 08:58:31 friends postfix/master[2933]:
May 28 08:58:31 friends postfix/smtpd[6301]: connect from unknown[59.95.173.59]

May 28 08:58:31 friends postfix/master[2933]: terminating on signal 11

A Dovecot daemon used to suddenly die on the same box too.
