from the original post:
ps aux | egrep "nfs|rpc" on the server returns this:
37 root [rpciod]
41 root [nfsiod]
132 root /usr/bin/rpcbind
194 root [nfsd4]
195 root [nfsd4_callbacks]
199 root [nfsd]
200 root [nfsd]
233 root rpc.statd
237 root /usr/sbin/rpc.idmapd
241 root rpc.mountd -V 3 -V 4

all the prints from the logs that I've found (/var/log/messages) exist in the previous mail I've sent.
is there another log I'm missing? if so, where can I find it?

Thanks.

Dagg.
