Hi,
First post here, but I've been lurking zfs-discuss the past 3 months.
I'm having a very strange problem with one of my CIFS shares. Other shares are
working just perfectly. When I browse my share from a Windows XP (x64, latest
SP and updates), i instantly see some very odd traffic that starts pretty much
instantly. As soon as I close down Explorer or goes to another share, the
traffic stops and everything works fine again.
I see around 5-10Mbit of traffic, and thousands (~10K/second) of tiny small
packets are transmitted back and forth, for every workstation/client. This is
generating a lot of interrupts on the fileserver, raising the load, all for no
obvious reason.
When I first saw this happening, I thought it could be some kind of indexing
thing going on, or generating some media preview of the data on the server, or
similar. But after looking at packets (and considering the huge amount of
packets getting transferred), I think it might be some kind of CIFS bug.
A quick video of what's happening is here:

and a dump of some of the packets, grabbed on the Windows client (192.168.0.61)
is here:

The server is an OpenSolaris (snv_133) with "zfs set sharesmb=on pool/fs" set.
Any ideas on what I could do about this? This started happening out of nowhere,
from day to day, and it's somewhat a deal-breaker for us, for running
OpenSolaris. Currently, with ~8-10 users browsing shares, I see around 100K
interrupts per second on the server.
kind regards,
Kasper
