[mythtv-users] mythpreviewgen, mythcomflag, backend restarts and other errors in my backend log

[John Nissley]

I am running the latest trunk version and started to have problems with 
my master backend stopping every now and then. I have systemctl start it 
back up but it causes issue with recordings. If I leave it alone to 
record and do not connect to it with any front end then everything is 
fine but some times when I try to connect with a frontend the cpu load 
goes crazy and the backend will restart.
Here are some errors that I am seeing:
mythcommflag: mythcommflag[16909]: C thread_unknown 
mythcommandlineparser.cpp:2595 (ConfigureLogging) mythcommflag version: 
master [v0.28-pre-2415-gd0b4a31-dirty] www.mythtv.org
mythpreviewgen: mythpreviewgen[17015]: C thread_unknown 
mythcommandlineparser.cpp:2595 (ConfigureLogging) mythpreviewgen 
version: master [v0.28-pre-2415-gd0b4a31-dirty] www.mythtv.org

And just before the backend crashes because of high cpu utilization I 
see this message:

Help please..... What could be causing this?
