The Backend crash randomly. Since an update on this Version. I am not sure to wait for an update, or to investigate time to find the reason. Are any one else with a large movie Database here who have issues with mythtv? Not the database itself, but my recordings have a disc space consumption of nearly 3 Terabyte.

Have no clue what's wrong. The Server Socket got closed and connections timed out. Nearly 15 Hours after starting the Server and 12 Hours past the last reccord.

Mythmetadatalookup:
Code:
 SendMessage mythcorecontext.cpp:488 (ConnectCommandSocket) - Connection to master server timed out.
                        Either the server is down or the master server settings
                        in mythtv-settings does not contain the proper IP address

 SendMessage mythcorecontext.cpp:1018 (SendReceiveStringList) - Reconnection to backend server failed


The Grabber still running and try to go on. So this is just an indicator about the time when the Socket got lost.

The Segmantation fault that Killed the Child PID 28195 was timely two hours before the server lost its socked. So i am not sure if this crashed the server. Ill try to rescan my transponders as suggested.
