on 9.2-stable nfs/zfs and 10g hang

[Daniel Braniss]

hi all,

All was going ok till I decided to connect this host via a 10g nic and very soon it started
to hang. Running multiple make buildworlds from other hosts connected via 10g and
using both src and obj on the server via tcp/nfs did ok. but running
	find … -exec md5 {} + (the find finds over 6M files)
from another host (at 10g) will hang it very quickly.

If I wait a while (can’t be more specific) it sometimes recovers - but my users are not very
patient :-)

I will soon try the same experiment using the old 1G nic, but in the meantime, if someone
could shed some light would be very helpful

I’m attaching core.txt, but if it doesn’t make it, it’s also available at:

thanks,
	danny
