Timed out
As you know Ganesha needs to talk to rpc.statd on localhost for granting an
NLM lock. The client IP address is 10.10.10.102 but statd is unable to
monitor. Ganesha waits for only 3 seconds for this, but the statd might be
spending too much time doing reverse DNS lookup. Maybe, have an entry in
the /etc/hosts for that IP address and see if that works. Increasing the
timeout maybe an option but I am not sure if statd needs a name for the
client's IP address.
Regards, Malahal.
