Spontaneous reboot problem

I have a teramac R310-1U from DNUK running 5.3-RELEASE-p1. It is the  
only server I have running 5.x. ISTR that the SiS chip set prevented me  
loading 4.x.

The uptime of this server is good unless its under heavy load. When  
MySQL (with InnoDB) is being worked hard, the server will reboot after  
a few hours. However, build world will not crash it.

I have added the following to rc.conf:


and the following to the kernel configuration file:

makeoptions DEBUG=-g
options     KDB

I have also connected a serial console to the serial port and logged in  
as "root".

I never get a dump file and I never get a message at the console. I  
don't know what else I can do other than strike this hardware vendor  
off my list and dump the server. This machine has already had its  
motherboard replaced.

Any clue would be appreciated.

Many thanks,

Final note: the spontaneous reboots do have a tendency to introduce  
data errors on the disk - however, it still fails even after the disk  
has been fully repaired.
