Subject: 2.6.4 e100 NAPI - dst cache overflow and network unavailability
Date: Fri, 09 Apr 2004 08:45:12 +0800 [thread overview]
Message-ID: <4075F218.90804@outblaze.com> (raw)
I previously sent email to the list about seeing dst cache overflows and
the kernel spewing gibberish (at which point the box usually needs to be
rebooted as you'd wait a long time for the kernel to recover) to serial
console.
For all those cases with different values in route/max-size,
route/gc_thresh and tcp_max_syn_backlog, I'd get the problems even under
sufficient network load.
However, I had NAPI enabled in the e100 driver then.
Turning NAPI off for the e100 driver has meant that the box has now been
up several days without any problems under heavy network load.
I have not tried out 2.6.5 with NAPI enabled but 2.6.5 without NAPI
enabled is stable.
