I've done some more testing on this. It seems that although pkill
doesn't issue an error message when the process isn't running, it does
return an exit code of 1 and logrotate doesn't like that.

I have solved this for now with a simple script that uses:

if [ $(pgrep -c mythlogserver) -gt 0 ]
then
/usr/bin/pkill -HUP mythlogserver
fi

Although I suspect this will not solve the problem of mythlogserver
running under a userid other than mythtv. That is not going to be a
major problem for me, as I rarely use the frontend at the time that
logrotate is running, and now I am aware of the situation I can avoid it.
