Dear Dave,
I have set my icmplim to 1024. When it was 200 I would sometimes get a
warning about an OPEN port RST - which was also strange to me (that it was
open not closed). I suspected that it was because 5% of my packets where
being dropped though.
The server is under reasonable load (networking wise) around 80-90mbits, but
the processor is 75% idle..
The other strange this is that a reboot solves this, and it takes around 1-2
days to happen again..
you can try to enable polling:
kern.polling.reg_frac=20
kern.polling.user_frac=10
kern.polling.burst_max=1000
and perhaps tune rx_processing limit:
dev.em.0.rx_processing_limit: 100
you can also look at all open sessions when the server is in trouble:
netstat -n
Kind regards,
Ingo Flaschberger
