Hi
I recently upgraded our list server to 2.2.13pre3 (from 2.0.35) and have started getting these kernel messages:
Sep 3 17:00:32 murphy kernel: eth0: Insufficient memory; nuking packet. Sep 3 17:01:33 murphy last message repeated 1341 times
It seems from the source fro the de4x5 driver that it is trying to call dev_alloc_skb which failes for some reason, so it drops the packet. This is a very busy machine, it typically has several hundred active processes (qmail) and handles about a half million outbound mails each day.
From what little I know about the kernel I guess it probably is not swapping agressively enough. The machine usualy has a free output of:
murphy{root}/home/jgg#free total used free shared buffers cached Mem: 63424 53724 9700 18060 9700 23548 -/+ buffers/cache: 20476 42948 Swap: 120924 2444 118480
But I think some of those procmail processes can really chew up ram fast.
So, is this a kernel flaw, or should I be looking at tuning one of the parameters in /proc/ ?
Also, the 2.2 kernel has made a -huge- difference to the speed of the list server, easialy twice as fast, possibly more!
Thanks, Jason
