next in thread | raw e-mail | index | archive | help
I'm getting a kernel panic every time I start getting traffic (~ 20Mb/s
total) to two squid processes. This was not happening with -RELEASE. I
upgraded on the advice that STABLE would decrease the %cpu spent in
system, which was much higher than that spent in user. The machine's
only fucntion is as a reverse proxy (2 separate squid processes to take
advante of both cpus).
Let me know if a dump would be helpful, or if there's anything I can do
to help.
Dual AMD Opteron system..

ps. I don't believe the problem is with a zebra/ospfd kernel
interaction. the open port RST responses are expected; i can explain
why if it would provide insight into the problem...
