Yes, it happened to me too on a Debian unstable machine with more than one
kernel, starting with 2.6.28 until now. I have a feeling it's a
Debian-specific problem rather than a kernel one.
you may both want to try
echo 16384 > /proc/sys/vm/min_free_kbytes
or some other value depending on your amount of ram. This change will
increase the minimum amount of memory available for network memory
allocations, which are called from softirq context to refill the NIC's
receive buffers.
Will give it a shot, the default was already pretty close to the
suggestion, 11441, if it recurs, will increase further.
Thanks,
Justin.
