Just went through the same problem. I had my "restartfronted" script attached 
to a specific button on my remote via irexec daemon. It used to work for some 
time, but then suddenly when I used it, it started 3 or 4 copies of the 
frontend. I guess this must have been caused by one of the regular upgrades 
of lirc or something.

Anyway, I found out that the script was really started several times for some 
reason, so I just made sure that the script won't run in parallel


mkdir /tmp/restartfrontend || exit 0
trap 'rmdir /tmp/restartfrontend 2>/dev/null' EXIT

pkill mythfrontend
sleep 2
pkill -9 mythfrontend
nohup mythfrontend >> $HOME/.xsession-errors 2>&1 &
sleep 5
rmdir /tmp/restartfrontend

Works for me!

CU, Joe
