I cannot tell where the problem is occuring. I have a few models compiled
after the kernel was built (it's a stock 2.2.5-15 on a Redhat 6.0 AMD K6
II 450 / 256MB), ksymoops couldn't find symbols for. Does it mean one of
them is the culprit?
The first happened at 5 in the morning. no much going on then. I was
downloading files to a nfs drive (served by this machine) at the time (or
shortly before) it dies.
thanks
charles
