[mythtv-users] segfault with 0.27.1

[Josu Lazkano]

Hello again,

I have no segfault in the logs, but I think that something crash in
the backend. The frontend desn't work:

2014-07-02 07:23:26.267196 C  Protocol version check failure.
The response to MYTH_PROTO_VERSION was empty.
This happens when the backend is too busy to respond,
or has deadlocked due to bugs or hardware failure.

This is what I have in the backend GDB:

Program received signal SIGPIPE, Broken pipe.

I don't know if this will help to the developers.

Regards.
