[mythtv-users] Random lockups on Mythbackend

Mon Dec 13 19:51:23 UTC 2010

On occasion the computer that has Mythbackend will lock up. This occurs 
once every couple of weeks and sometimes three or four times in a row. I 
have done a web search as well as looking through the archives of Mythtv 
and found nothing that comes close to the problem I am having. This 
leads me to believe that I have a setting that is completely 
inappropriate or I have a hardware problem, but this is the only failure 
that I have seen. I am running Fedora 13 with Mythtv .24 with all 
updates for both and 1 Gig of memory. The following snippet from the 
Myth log file may point to a problem but I do not understand what it may 
be indicating. star9.home.com is the computer with Mythbackend.

At this point the computer locked up. The keyboard was locked up as well 
and I could not remote login from another computer either. I had to 
press the reset button.

Thanks,
