Suddenly yesterday my mythtv-backend system starting behaving
strange. I am running mythtv 0.25 with fixes from the mythubuntu
repository. I can't tie this change with any update from the
repository<br>
<br>
1) Connect with myth-frontend (from another machine) hangs when
trying to connect to anything to do with the backend. If I try to
contact the recordings it even slows the fron tend down so it almost
does't respond to keys (it takes at least 10 seconds to respond to
each key). Watch TV respons with "All Tuners Busy". I can't exit
the program without forcing it to be killed by the window manager.<br>
<br>
2) Mythweb can't display even the TV listings. It seems to be slowly
coming up with the contents of the next channel every 30 seconds or
so<br>
<br>
At the top of the screen I get the following - it think for each
channel as it is displayed<br>
<br>
<b>User Notice</b> at
/usr/share/mythtv/bindings/php/MythBackend.php, line 105:<br>
!!NoTrans: Unexpected response to MYTH_PROTO_VERSION '72': !!<br>
<br>
Although I had been trying to restart the front end (using the
Ununtu "service myth-backend restart" command I discovered that the
main process was not dying.<br>
<br>
<br>
--------------<br>
<br>
A bit later ...<br>
<br>
I have now killed the main backend process - needed a SIGKILL to
kill it - and restarted and I seem to have everything back working.
It seems to be related to the HD recordings that I was making at the
time it went wrong yesterday. Each one is precisely 376B long<br>
<br>
<br>
<br>
This was the first time I tried multiple HD recordings using the
Pinnacle 290e USB stick. This is connected to the PC via a USB 2.0
Hub (I wanted to make sure it had enough power).<br>
<br>
I don't suspect that the number of records with that has any effect
since, if I understand things correctly, we are just pulling the
multiple channels from a single stream.<br>
<br>
The issue could be trying to write the multiple HD channels to the
disk at the same time.<br>
<br>
Has anyone else experienced this sort of problem?<br>
