Marcel,

I had a server doing just that (PIII-733, 768MB RAM, Tekram SCSI with 2
drives, Intel 440BX, 4.2-STABLE with softupdates).

What "fixed" it was to recompile the kernel, taking out SMB and I2C. I
later upgraded it to 4.5-STABLE, and it still runs fine. Unfortunately, I
can't experiment with the server to see if in actual fact it was the SMB
and I2C components that were the culprits, so I don't know for sure what
caused the spontaneous and frequent reboots.
