[mythtv-users] Mythfrontend losing connection to backend

[mythtv.users]

Anyone have a clue why my frontend keeps losing connection to the backend?

Both are on the same machine (as is the database), the backend is still
up, a restart of mythfrontend and it works again.

Here is the section of the log where it loses connection

Any ideas?

I'm running suse 10.3, mythtv 0.20.20070821-1

Thanks
