Hello. I'm running mythbuntu 10.10, myth 0..23-fixes and I am getting
some random, intermittent issues recently. Having lost my frontend a
while back to a water spill I'm currently mainly using my backend via
mythweb and downloading files to my laptop to watch. My backend also
runs email, a wiki and monitoring via cacti. Every so often it seems
that parts of the backend process fall over. <br>
<br>
The main symptoms are that the cacti trace for tuners in use goes to
zero (i.e the tuners disapear). at the same time the 'Upcoming
recordings'page of mythweb shows no upcoming recordings and I get this
error if I try to open the status page of MythWeb;<br>
<snip><br>
</blockquote>
<br>
<br>
It's still happening, and I would love some help, or advice on where to
look. Here's the latest mythbackend.log file, where it looks like the
tuners disappeared sometime between 20:40 and 21:00; Fe rom this I see
the IOBOUND error which might suggest that the system can't move data
from the two USB tuners onto the disk (recordings are stored on an
external USB disk.<br>
