Hi,
This keeps finding the same place to crash. I don't have enough data points
for real statistics, but these recent results suggest that I was better off
running the earlier part of the 2.2.15pre series and merely having
/proc/sys/net/tcp_keepalive_time set way high (which it still is, by the
way) than I am with the 2.2.15pre17+ kernel code and its tcp improvements.
Seems I'm getting twice the crashes now. Then again, this could just be
chance - traffic is up a bit too - and we _have_ gone from the previous
NULL pointer request failure to a paging request failure, which may be some
sort of progress??
The latest Oopsen follows for comparison.
