I have had 2 lockups in the past month with SMP on Intel STL2 MB. I am wondering
if network problems may have something to do with my problem. The last time it stopped
responding there was major network problems right before it stopped. I also had a non
SMP box stop responding during bad network problems. On this box I was able to log in after I redirected
all traffic to another box. When I checked netstat -m, mbuf clusters had peaked at 4608 which
is usually only around 2000 mbufs. When there is lots of packet loss is it possible to eat
up all mbufs? Should I beef up mbufs more in case of network problems?
Thanks,
Brian
