Thanks for the reply, Dan.
I have captured packets (tcpdump) between the hosts, and I'm enclosing
that as an attachment. I'm not facile enough with tcpdump to capture
only the significant packets, so I just got everything.
I've enclosed the dump as an attachment - physics is the FreeBSD
machine and cfpa11 is the Solaris box. Actually, in this case, the
program only locked the file, no unlock, and it hung anyway. (This
is different from before.)
Is this output helpful?
Thanks.
Steve
