CentOS - Feb 2010 - cannot mount NFS share, portmap problems, what todo?

Hi all,

I want to map an NFS share from a remote server to a local CentOS 5.4
server, but have a problem with portmap:

root at mercury:[~]$ service portmap restart
pmap_getmaps rpc problem: RPC: Unable to receive; errno = Connection reset
by peer
Stopping portmap:                                          [FAILED]
Starting portmap:                                          [  OK  ]
root at mercury:[~]$ service portmap status
portmap dead but subsys locked
root at mercury:[~]$


What is "subsys", and how do I "unlock it"?



/var/log/messages gives me this:

Feb  3 13:44:23 mercury portmap[2221]: cannot bind udp: Address already in
use


Which address is it referring to? Portmap isn't running so I don't see
how
it can be in use. Or should I be looking for the problem elsewhere?

Google search results sugested opening port 111 in the firewall, which I
have, but still get the error. And I cannot, at any costs, reboot this
server. So, is there a way to fix this?

The first thing I would do is to see if there is something running on the
portmap port:

 

# netstat -ap --inet

 

Check for sunrpc (which is the service name associated with the portmapper,
as listed in /etc/services).

Check if there is lock file for portmap under /var/run and remove it
and try again.

Use also netstat -lp --ip to check if portmap is already running.
