System Panic (Trap 12)

[James Nelson]

I have posted this message to hackers but have not gotten a response.  I think this is networking related, but I don't know how to solve it?  Any ideas?
	
	I am getting numerous panics.  It seems to be totally random with no bearing on load.  This is a dual proc. AMD 2600, 2 GB Ram.


I have included the where results of three seperate core files.

Please advise.

Thanks in advance.
