Note: I've updated the script as follows:

Script updated on August 2 to also restart gdm anytime backend is restarted.
Script updated on August 5 to make timestamp on captured mythbackend log file match timestamp in mbemon.log.

I made these changes in the second post on this thread where I posted the original script.

Note: This script has executed 2 automated restarts for me spread over a period of 3 days. Based on reviewing the captured logs I believe I hit the problem where the backend will sometimes go sideways when it tries to generate a preview from a bad ".nuv" file. I have since identified and removed that bad file.

After several weeks of stability in my backend I have suddenly encountered a new problem -- one that the monitoring script was not able to detect. I've modified the script to detect this new condition and effect a restart. I made this change in the second post on this thread where I posted the original script.

In the meantime, I continue to try to figure out why I am having a new back-end problem, as discussed at http://mysettopbox.tv/phpBB2/viewtopic.php?t=11243

The scripts will be included in the next release. However, they won't be started by default. I've simply included them for those that want to use it. When the next release is ready, perhaps you can write a page on the wiki.

That's great -- it's nice to feel that I've been able o contribute something back to the communiity! I'll write something up this weekend in the Wiki and then post a link to that writeup on this thread.

marc, cesman, tjc, et al,
I did this to /usr/local/bin/mythbackup:

Code:
# Start with the database backup, first we make sure it's healthy, and
# then we can dump it.
# Doing this while the backend is active would be BAD.
/etc/init.d/mbemon stop
/etc/init.d/mythtv-backend stop

# Stop, check, and fix $DATABASE db to ensure clean copy, then restart it.
/etc/init.d/mysql stop
cd $DATABASE_DIR
myisamchk -f *.MYI
/etc/init.d/mysql start

# Dumps the $DATABASE database
mysqldump -c -u root $DATABASE > $BACKUP_SQL

# Now we can restart the backend.
/etc/init.d/mythtv-backend start
/etc/init.d/mbemon start


I figured that since I use mythbackup often (from the command-line), I might forget to stop mbemon.
Anyone see any problem with this?

Good idea! No, no issues.
