Comment 3 for bug 1000771

Nope, no CEC, honestly not even sure what that is? I have 2 myth boxes, one
is the FE/BE and the other is just a FE. The problem started when I use
irexec to launch a script I wrote, but after a while it won't even launch
just using the links in the menu or via command line.

Script that irexec calls:
#!/bin/bash
# Test to see if MythTV is running first
if ps -ef | grep xbmc.bin | grep -v grep; then
killall -v -s9 xbmc.bin
fi
if ps -ef | grep mythfrontend.re | grep -v grep; then
# Do nothing
echo “MythTV already Running!”
else
# Startup MythTV
mythfrontend
fi
exit

I was constantly getting a 139 crash error, but just found out that was due
to timezone issues. Both FE and FE/BE are now synced with a local time
server so that error seems to be gone, but I can't get mythfrontend to
start now.

I use the same script on the FE/BE box, and it works flawlessly with no
segfaults.
