Is this happening the same time, nearly, every night ? If so what cronjobs are running at that time ?

Regards,

Subject: Kernel crash, MailScanner mentioned 

Hi guys, 

I realise this might not be caused by MailScanner, but I've got a server 
running SLES 10 SP1 i586 that's crashing nearly every night. 

In the logs I see it does mentioned something about MS, but not sure if 
this means that it's actually MS causing the problem. 

The kernel it's using is "Linux mail 2.6.16.46-0.12-smp #1 SMP Thu May 
17 14:00:09 UTC 2007 i686 i686 i386 GNU/Linux" 

If anyone could point me in the right direction I'll be more than grateful. 

I can't run an update on the SLES as it's not registered yet, as the 
client only wants to register in the new year, but needed the server 
straight away.

I'd run memtest on the server for as long as you can, e.g. 12 hours.
