Here are the last couple of lines from the output:

stat64("/nsr/debug/nowritev", 0xbfffe078) = -1 ENOENT (No such file or
directory)
stat64("/nsr/debug/noreadv", 0xbfffe078) = -1 ENOENT (No such file or
directory)
stat64("/nsr/debug/nodelayeor", 0xbfffe078) = -1 ENOENT (No such file or
directory)
geteuid32()                             = 0
socket(PF_INET, SOCK_STREAM, IPPROTO_TCP) = 5
bind(5, {sin_family=AF_INET, sin_port=htons(22485),
sin_addr=inet_addr("0.0.0.0")}}, 16) = 0
connect(5, {sin_family=AF_INET, sin_port=htons(7938),
sin_addr=inet_addr("##.##.###.###")}}, 16

It hangs right at the ", 16"

I substituted '#' for the actual ip address that was shown. I should
note that this is the ONLY ip address listed in the output, AND it's not
the client's ip, the storage node or the primary server's ip. Oddly,
it's some other machine that has no connection with backups whatsoever
and is currently unreachable by ping. In fact, I think it's powered off.
When I run 'strace -o /tmp/foo savefs -p' on another host (one that's
acting normally), I see three different ip addresses listed: primary
server (many times), client (once), and the machine that the client is
ypbound to (many times). Not sure if that's any relation to why it shows
up in the output since it has no direct affiliation with the backups
(it's not a storage node server or anything), but from what I can
observe, the only IP address that's showing up in the output that I get
on this weird host is an ip for a host that's not even alive.
