We've had several users who noticed issues with the DB disappearing out 
from under Myth, but we haven't been able to reproduce the issue or 
track down its cause.  The closest we've gotten to it is 
http://svn.mythtv.org/trac/ticket/6544 , but unfortunately the Qt debug 
symbols weren't available/loaded when the backtrace was made, so it's 
hard to tell what was happening.

/Very/ interesting.  If you can figure out which caused it, please let 
us know exactly how it was monitoring mythbackend (polling the status 
port or using the bindings to send a "ping" to the backend or ...).

I don't know if Stuart was/is using nagios or monit when he saw the 
database failure, but I'll ask.  (TTBOMK, he only saw the one.)

Thanks,
