(kgdb) q
Rather than pasting the decoded tcpdump output here, the raw capture
file is at http://www.tmk.com/transient/rdump30.gz (it is only 76KB
compressed, 270KB uncompressed). It looks to me like the remote host
(the VMS box) has correctly ack'd all outstanding data from the FreeBSD
host, but that the FreeBSD host is just sitting there for some reason.
As before, I have this sitting in the wedged state so if anyone needs
more data, I can either collect it or give you access to the system.
