Well, I can see the delays in the capture, but the snarflen for the
capture is a little too small to tell much else. Can you redo the
capture with a larger snarflen (maybe -s 512 or so)?
Also, were you able to tell anything from a server-side capture? Is the
server issuing oplock breaks at those times?
Cheers,
Jeff
