Test socket-11.8 fails with message:
couldn't open socket: address already in use
This problem is caused by the socket at port 4003. This port is when NFS is configured to used fixed ports:
rquotad is an rpc(3N) server which returns quotas for a user of a local filesystem which is mounted by a remote machine over the NFS.
Changing 4003 to 4006 solved the problem.
