    Myth frontend crash when trying to display recordings after watching a recording

    I'm running the backend and frontend on 2 seperate PC's over a 100mb network connection.

    I can connect to the backend from the frontend without any problems.
    But after watching a recorded program the frontend sometimes crashes when I stop playing the recording and it tries to display the list of available recorded programs.

    It just displays "select program" or what ever the text is in English (I', running the Mythfrontend in German) for about 4 seconds without showing any programs, then just crashes out to the desktop.

    If I just restart Mythfrontend everything works again until I repeat the process above. Note the frontend crashes if I exit the watch recording using the Stop button on my remote or if just let the recording end normally.

    I've checked my network connection and it's 100% ok.
    I can't see anything strange in my Backend log.
    I don't appear to have a frontend log!

    It looks to me as if the frontend it trying to make contact with the SQL server on the backend and for some reason it can't and just dies.

    Edit: If I watch a recording for only afew minutes and exit back to the recording list the frontend doesn't crash. But if I watch a 2 hour film it crashes about 50% of the time.

    Currently running Mythbuntu 7.10 on the frontend with all the lastest updates as of 17.1.2008 and Gutsy 7.10 on the backend also with all the lastest updates as of 17.1.2008.

    Anyone got any ideas what the problem could be? Solution maybe?

    Edit 2: I'm running 64Bit ubuntu on the backend. 32bit on the frontend and a Nvidia G7300 graphic card with the Nvidia drivers (not open source) on the frontend.

    Regards

    Ok I've just been able to reproduce the crash, with logging enabled.
    Here's the mythfrontend.log:-

    Maybe I should try and create a bug report.

    Re: Myth frontend crash when trying to display recordings after watching a recording

    Hi,

    Just gone over to the weekly builds, and exactly the same error.

    Am I talking to myself here? Is anyone actually reading this.

    Regards

    Re: Myth frontend crash when trying to display recordings after watching a recording

    Sometimes I've noticed the backend likes to crash after I've left watching tv mode, done something else, and tried to come back to watch tv mode ...

    So I think I sort-ish-kinda know what you're feeling (granted, I know your frontend is crashing, not backend).

    What I did, since I've no idea why in the world the backend does this, is create a script that checks to see if the backend is running every 30 seconds and restart it if it is not ... at the very least I don't have to get up and mess with it to restart the backend.

    Perhaps you can find an idea in that. But ultimately, I don't know what's up with it making it do these things.

    Good luck.

    Re: Myth frontend crash when trying to display recordings after watching a recording

    Hi,

    I could use a script that restarts the frontend when it dies, but that's just fighting the symtom rather than "curing the problem".

    I've started going through the MythTV bug list looking for anything that looks like my problem. But I've not found anything yet.

    Regards
    Ian Dobson

    ps. I've not had any problems with my backend, it only crashed once on me but that was my fault (I was playing with the mysql database and screwed up afew settings).

    Re: Myth frontend crash when trying to display recordings after watching a recording

    OK,

    I've finally been through the SVN bug list and found this :- http://svn.mythtv.org/trac/ticket/4148. It looks as if the problem is solved, I just need to wait for the weekly compile to be updated.

    If that doesn't happen then I'll try backporting the patch myself. It doesn't look like it's a major change as it shouldn't take all to long to implement.

    Regards
    Ian Dobson

    Re: Myth frontend crash when trying to display recordings after watching a recording

    Bump.

    The SVN patch doesn't look as if it's my problem.

    Using Standard xV and the kernel Deinterlacer seems to have "improved" the problem. It only happens once in about 20-30 times.

    OK. I've also optimized my MySql backend (More cache for the Query buffer).

    Regards
    Ian Dobson.

    ps. How often are the weekly builds "built"? I've not seen an update for over a week now.

    Re: Myth frontend crash when trying to display recordings after watching a recording

    I know this is a very old post; however, In case anyone comes across this, I had this error on 10.10 myth .23 It turns out, I had the Nvidia driver/modaliases installed from a different video card. Purged the Nvidia drivers (as I'm now using an ATI HD4350 HDMI) and SUCCESS.
