i 'll take the chance here,
i've captured instances of netstat -m which reported 99% (even 100%) in use
and occasionally the machine crashed (and then i couldnt tell of course) and i was suspecting that "running out of mbufs" could well be the reason.
At least that's what i liked to think since we are talking about "sligthly" modified TCP code with several connections opened simultaneoulsy with
large cwnds (around 17K each if i remember well).
Am i right in assuming :
- "100% in use" will cause a crash ?
- the way to increase memory allocated to network is
options "NMBCLUSTERS=XXXX" ?
Cheers,
Panos
