[OpenAFS] OpenAFS 1.4.1 and Solaris 9 "hangs"

[Jeff Blaine]

Any ideas would be great.

We're experiencing odd "hangs" in vos commands.
-- Nothing logged to /usr/afs/logs/*
-- Nothing logged to syslog
-- Solaris 9 on all boxes in this testbed
-- OpenAFS 1.4.1
-- ping between all boxes is a constant 0ms
-- No router is involved

Running "apptrace vos examine u.jer", for example, worked fine
6 times in a row.  The 7th time resulted in a series of the
following blocks and took a full 1m45s to finish (successfully).
Note the "dangling" open paren after the call to
select_large_fdset.  This is where it hiccups for a second or
three before spitting out another big block of this.
