We have 6 servers :Dell6400+DEll220S(disk array) for mail system storage. , they use the same OS and act as the same role , but one of them always crash again and again .
in the /var/logs/messages there are many reports such as below:
----------------------------------------------------------------
Sep 25 06:00:00 bj153 /kernel: pid 11263 (cron), uid 0: exited on signal 11 (core dumped)
Sep 25 06:02:46 bj153 /kernel: pid 11270 (ldmsapp), uid 1001: exited on signal 6 (core dumped)
---------------------------------------------------------------
there is no cron jobs at that time; ldmsapp is a cgi ,but other servers use the same cgi program without problem.

 This looks like a hardware problem of the specific machine, but...
 
 . Is it always these two programs (cron and ldmsapp) that are failing?
 
 . Can you build a version of cron with debugging symbols, and use
   gdb to get a crash dump of cron after it has failed?

 I have to agree, definitely looks like a hardware (cpu/mobo/memory) 
 problem.  Can you run the mersenne torture stress test without incident?

 If not, I'd suggest taking a hard look at your memory.  Are these 
 machines in their stock Dell configuration, or has the memory been upgraded?
