It will be running a process with a name of the form "<server IP
address>-manager", and will be running the function
nfs4_run_state_manager().
BTW: Do you have the following patches applied?
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git&a=commitdiff&h=b0ed9dbc24f1fd912b2dd08b995153cafc1d5b1c
and
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git&a=commitdiff&h=ae1007d37e00144b72906a4bdc47d517ae91bcc1
They are not yet in the stable kernel series, AFAIK, but are slated to
be merged soon.
Cheers
Trond
