Yup. Went through several SIMMs. Just about the only thing we *haven't*
replaced is the hard drive. However there are several local Linux ISPs
which have the *exact same* problem, on completely different hardware and
motherboard, etc. and they have also gone through motherboards, cards, etc.
so I don't think it's the hardware config -- I definitely think it's in
the kernel.
If someone can't find the cause of the problem, I'm afraid we'll have to
ditch Linux and go with FreeBSD. Pity, coz otherwise Linux is very nice.
