Do you have anything blocked on IO?
While I was working on the infiniband stuff, I often ran into problems
where things could get blocked on IO/network-traffic and cause servers
to spin (polling for new data which never comes).
There were also some issues that I came across where the kernel module
would hang because an MD server was hung/spinning/dead.
Usually restarting the server processes cleaned this up on the client-side.

If you cannot kill with a -9, IMO:  you are blocked on IO or inside
kernel land which implies a bug at some level.

Im not sure if you've described it in detail already - I havent been
in #pvfs2 for a while - but can you describe your setup in gross
verbosity?
Also, untarring on-the-fly on pvfs2 can be pretty brutal, and I seem
to recall we highly recommended not running binaries from the pvfs2
filesystem - not sure if that has changed ?
