Hi, this may not be correct mailinglist for this, but I''d like to share
this with you, I noticed weird network behavior with osol snv_123.
icmp for host lags randomly between 500ms-5000ms and ssh sessions seem to
tangle, I guess this could affect iscsi/nfs as well.

what was most intresting that I found workaround to be running snoop with
promiscuous mode disabled on interfaces suffering lag, this did make
interruptions go away. Is this somekind cpu/irq scheduling issue?

Behaviour was noticed on two different platform and with two different nics (bge
and e1000).


Unless you have some specific reason for thinking this is a zfs issue, you
probably want to ask on the crossbow-discuss mailing list.
