Freebsd 5.3 hangs under heavy load????

[Amandeep Pannu]

Hi all,

I have two Seagate SCSI drives 36GB and 8GB RAM and installed 5.3-REL with
PAE and SMP support.
Now the problem arises that the system hangs under heavy load and there
are no error messages nothing. I have to hard boot it everytime it hangs.

Any ideas what is going on.
It is a Supermicro MB.
2GB PC2100 DDR266 ECC/Reg
Intel Xeon 2.4 GHz 533FSB

Thanks in advance.
