[Bug 330272] Re: mythbackend silently fails with QSqlQuery::exec: empty query

[Kelvinelk]

The error which i get are similar in format to Kyle's. It seems to
happen mostly in the middle of the night but it has been happening for
some time, around the time that it was first reported by Kyle. It is
only recently that it seems to be getting far more frequent.

Background to my mythtv setup:

I have been running mythtv for a couple of years now, initially using
the packages that came with ubuntu, then moving to the weekly builds
from mythbuntu. I have a remote frontend and the backend sits on a
private subnet. EIT is used to collect the radio information only on
DVB-T. Tuner card is a Hauppauge Nova-T 500.

The issue always seems to occur when the backend _appears_ to be idle,
but perhaps it is actually doing some housekeeping or something in the
background? I am reluctant to start using 0.22 and wait for the bug to
occur as we record things daily and any database backup will quickly be
out of date.

For now I will try alistair's trick of turning off the jobqueue thread,
and if that doesn't work, try running backend with --nohousekeeping
also.
