nlm: do not use killall command to kill rpc.statd
killall command will kill the rpc.statd process only in normal mode.
If the process is running in valgrind mode, then killall is not able
to kill rpc.statd and several instances of rpc.statd will be running
for every restart of the nfs server (graph changes etc).
So to avoid that get the pid of rpc.statd using /var/run/rpc.statd.pid
and send SIGKILL signal to that pid to accomplish what killall command
was doing.
