Would it be possible to post a bzip2 binary tethereal network trace?
Something similar to:

    tethereal -w /tmp/data.pcap host <server> ; bzip2 /tmp/data.pcap

Hi


By a pure coincidence i found a fix for a becoming stale connection

The solution for me is to declare export with a real ip of the server

/storage/d4     192.168.100.*(rw,sync)
/storage/d4     192.168.100.220(rw,sync)

After adding the line 220 ip address , the mount staying in place

Is this of any help , do you still need a dump ?

Yes.. if you would mind taking the time... 

It appears this could be a DNS issue, so having a 
trace will hopefully prove that theory...

Closing as not a bug since there seem to be a solution...
