I recently upgrade my mythbuntu to 9.10 and sametime it upgraded mythtv 
from 0.21 -> 0.22. Now I get consistently hangs on backend. Backend 
is running but doesn't respond to frontend or mythweb. It seems that mysql  
connections start hanging. Can anyone give hints where I should 
start looking for possible errors? Usually these are last things I see in

As you can see I trying latest fixes from mythbuntu repository but they 
haven't helped so far.

I also found these with one hang but they haven't happened since:
Query was:
SELECT chanid, useonairguide FROM channel, dtv_multiplex WHERE serviceid        
= ?   AND       networkid        = ?   AND       transportid      = ? AND       
channel.mplexid  = dtv_multiplex.mplexid AND channel.sourceid = ?
Bindings were:
Driver error was [2/2006]:
QMYSQL3: Unable to execute statement
Database error was:
MySQL server has gone away

MySQL was running and errors disappeared when I restarted backend.
