screwed by linux again. sigh.
so apparently i am overloading my pathetic linux system with too much
tcp/ip traffic.
is there any way to detect this while (or before or after) it is
happening?
of course no error messages are emitted.
but might there be some other thing buried away somewhere, like /proc?
thanks
Is it possible that you are running into an interrupt processing issue?
Is it lots of small packets? Does top show one CPU more heavily loaded
than others? Depending upon your NIC, you could have options for
interrupt coalascing and spreading them around your cores evenly, as
well as configuring the interval at which the NIC buffers packets,
handling interrupts, and passing them up to the host after a defined
interval.
itop may be an option, if you have it or can build it. Else you might be
stuck trying to interpret /proc/interrupts.
