I have just upgraded to 0.22-svn through pacman and I can't get the backend to start. The backend log continues to repeat: Code: 2009-12-05 22:53:10.842 mythbackend version: branches/release-0-22-fixes [22783] www.mythtv.org 2009-12-05 22:53:10.844 Using runtime prefix = /usr 2009-12-05 22:53:10.845 Using configuration directory = /home/mythtv/.mythtv 2009-12-05 22:53:10.847 Empty LocalHostName. 2009-12-05 22:53:10.851 Using localhost value of mythtv 2009-12-05 22:53:10.861 New DB connection, total: 1 2009-12-05 22:53:10.868 Connected to database 'mythconverg' at host: 192.168.254.100 2009-12-05 22:53:10.869 Closing DB connection named 'DBManager0' 2009-12-05 22:53:10.871 Connected to database 'mythconverg' at host: 192.168.254.100 2009-12-05 22:53:10.877 Current MythTV Schema Version (DBSchemaVer): 1244 2009-12-05 22:53:10.880 MythBackend: Starting up as the master server. 2009-12-05 22:53:10.885 New DB connection, total: 2 2009-12-05 22:53:10.888 Connected to database 'mythconverg' at host: 192.168.254.100 2009-12-05 22:53:10.891 mythbackend: MythBackend started as master server 2009-12-05 22:53:10.902 New DB connection, total: 3 2009-12-05 22:53:10.903 Connected to database 'mythconverg' at host: 192.168.254.100 On a side note, also VNC is running like a dog, that is when it works and I am on a GB LAN, but first things first.

After I did a full reinstall of 6.01, I had an issue where mythbackend was crashing and sv would keep restarting it over and over again. This sounds like what you are seeing too. I had mucked something up. I ended up tweaking something and fixed it. I can't remember if it was my /etc/my.cnf (MySQL) with my IP address, or something else. From a command line, I ran "mythbackend -v all" for lots of debug output and I believe it pointed me in the right direction. It might have been my HDHomeRun (I have it shared between two machines) and it was crashing when trying to tune a channel. Unfortunately, I can't remember exactly.

I removed my HDHR -0 tuner and this allowed everything to move forward. Could be a bug, but I have not had time to investigate further. Maybe others with HDHRs will come forward. You might want to delete your tuners and add them again. I noticed a bogus tuner is still reported in mythweb. So, I need to look into this. Probably database issues from the 0.21 to 0.22 conversion or such (since I started clean).

It is related to the HDHomeRun as if I delete the HDHR tuners the backend starts fine. I did find this bug report: http://cvs.mythtv.org/trac/ticket/7624 that relates the exact problem that I was having. From looking at the version that we have I don't believe this patch is in it. Something to be very wary of I think.

Girkers: Did you get this resolved? You say the backend started when you dropped the HDHomeRun tuners, but were you able to add them back? I'd like to go to 0.22, but cant' do it if it puts the HDHomeRun out of service. Craig

Not at the moment, as soon as I add them it won't start. When I find time over Xmas I plan on doing a fresh install and an upgrade straight away, but this is a little ways off yet. Sorry I can't be much help to you.
