[CentOS] Misterious hang

Hi all,
Recently one my Centos 5.7 VM just crashes at least once a day randomly (hang).

In /var/log/messages there is nothing at all that there is problem (no
error, no failure). The log just stops.

The only change I did before this crashes is I activated LDAP
authentication, and also auditd. But I don't see any evidence relating
to it.

Any clue where to look for the cause?

Thank you.
