[clug] MythTV backend uncommunicative

Hi all,

I've recently upgraded my home server to CentOS 6 and MythTV 0.25, and all of
a sudden my MythTV backend is just not responding to network traffic.  I can
see the TCP handshake, and the front end or other program sends its MYTHPROTO
handshake, but the backend just never seems to respond and, from strace and
mythbackend's debugging, it's like the packet never actually gets received.

Has anyone seen anything like this before?  I'm kind of stumped at this point
- - I know that there's something going wrong here but I have no idea what may
be causing it.

I've checked the firewall - the machine's firewall isn't preventing the packet
from getting through.

netstat says that the program is listening on port 6543 on all interfaces.

mythbackend --printsched -v all and similar shows that the program is able to
talk to the database on port 3306.

Any ideas of things I can pursue to fix this would be greatly appreciated,
because I'm at a bit of a dead end.

Thanks in advance,
