The system was not rebooted, it just was not responsive (ssh) and has a gap in logfiles for 15 minutes. After 15 minutes it started responding.

Hi All.
I had today a problem with my mail server (2.6.18-274.12.1.el5 #1 SMP Tue Nov 29 13:37:35 EST 2011 i686 i686 i386 GNU/Linux, CentOS release 5.7 (Final)). On my Cacti graphs I see that there has been much I/O write on the disks and then there is no more info. Also in logs (messages, dmesg, netconsole) there is no info for about 15 minutes when there was a
problem
with the server.
I would like to have some info in such situations. Do you know any solutions?
Your description is unclear. Did the system recover, or did it have to be power cycled or otherwise rebooted?
A hang with no log information can sometimes be caused by driver issues.
The first thing to try is a "yum update" to the current and supported version 5.8.
