[Pvfs2-developers] Hang at server shutdown

[Murali Vilayannur]

Hi Scott,
Just a shot into the wild...
Can you do
% mv /lib/tls /lib/tls.old

and then rerun the server with valgrind..
Quite possibly this is a valid bug in pvfs2, just wanted to find out
if the error message is any different after you do the above..
Don't forget to revert the rename
% mv /lib/tls.old /lib/tls
after you are done.
thanks,
Murali
