I think this is probably related to some of the changes we added
recently that are supposed to allow in-progress operations at the
server to complete when it receives a SIGINT. Simply allowing them
to complete appears to have expressed some bugs esp. if the client is
gone.
Thanks for the detailed report, I'm assuming the same behavior occurs
with tcp as well, but I guess you've only tried with ib?

I did pvfs2-cp from client to server, ctrl-c'd the client

The client log looks like it handled everything correctly, and de-
registered all the memory and etc. that it should have done. Not
so lucky on the server I think, this is the log from the MD server,
which is the only one that went down, the Data servers are all
still up.

Is this the expected operation when a client 'dies'? I've seen in
the past that simply killing the pvfs2-cp process hasnt caused
server's to go down, but maybe I'm wrong?
