 I had noticed the restarts (under systemd the process is set to restart on
 fail) but that was before I realised they were occuring as the SB was
 starting recording (the MB is not used for recordings). I tried to run
 mythbackend under gdb as the normal user but it got "problematic", i.e. I
 couldn't even access it through mythweb. So I continued running it
 normally via systemd (which still runs it as a normal user) and then I
 noticed in the system logs when it was restarting. Sorry for the
 monologue...

 I am enclosing the relevant syslog entry from a restart. "al2kpro" is the
 name of the SB. If this doesn't help, please let me know and I will try to
 run the master mythbackend as root to see if it's more responsive.

 If these are not enough and you want gdb logs, what log options should I
 enter (i.e. network,socket. etc)

 Best regards,
