and the frontend log lines that might be important:
Aug 31 11:41:20 mythuser-ZBOX-ID84 mythfrontend.real:
mythfrontend[18253]: N thread_unknown mythdirs.cpp:194
(InitializeMythDirs) Using configuration directory = /home/mythuser/.mythtv
I found no config.xml file in that directory.
So I created one:
mythuser at mythuser-ZBOX-ID84:~$ cat .mythtv/config.xml
<Configuration>
<Database>
<PingHost>1</PingHost>
<Host>192.168.0.105</Host>
<UserName>mythtv</UserName>
<Password>Tj4zOBwM</Password>
<DatabaseName>mythconverg</DatabaseName>
<Port>3306</Port>
</Database>
<WakeOnLAN>
<Enabled>0</Enabled>
<SQLReconnectWaitTime>0</SQLReconnectWaitTime>
<SQLConnectRetry>5</SQLConnectRetry>
<Command>echo 'WOLsqlServerCommand not set'</Command>
</WakeOnLAN>
</Configuration>
and it still crashed:
