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.
