[eepro100] KERNEL: assertion (flags&MSG_PEEK) failed at tcp.c(1463)

Donald, thanks for your prompt reply.
I've another server down with the same rx buffer problem again. The funny
thing is both servers were down in the morning (5-6 am) where processing
is the lowest. Don't really understand why the kernel has not enough
memory for the network card... Have tried the eepro-diag to see the card
'sleep mode' has been turn on and the results is negative.
Will tuning VM solve the problem? What are the possible side effects? I
still have a couple of server (with similar configs) and I'm not sure if I
should tune the VM, as a preventive messure. Please advise.
