Can't access Media Server and errors in log

I am having various problems with my My Book World Edition 2 and I hope someone here might be able to assist.

Firstly the media server doesn’t seem to be working - neither my XBMC media server, nor my Samsung Smart Hub TV can spot the twonky server, and if I click on the “Media server” link through the device admin pages, it just times out.

Secondly, the log is showing a load of errors.  For example:

I don’t know if they’re related, but I’d be grateful for any assistance or thoughts as to what the issue could be.

Many thanks in advance,

John

Just to add I downloaded a port scanner and ran it on the IP of my MyBookWorld - the only ports open are 80 (www-http), 139 (netbios-ssn) and 445 (microsoft-ds).  So the 9000 port (that I think Twonky runs on) isn’t up, suggesting the Twonky server isn’t running.  I have tried unplugging and reconnecting the server, and rebooting through the WD admin pages, but still can’t get Twonky to appear.  Any ideas?

OK so a solution to not being able to get to the twonky server - turns out it was my internal firewall on the router that was blocking things accessing the twonky server.  So I’ve disabled that and it now gets picked up fine.

However the error logs are stil appearing, so grateful for any thoughts.
