Backend seems to be dying, but nothing in the logs is showing me why. What I have done:
Repaired mysql tables
Checked HD space (df -h)
/dev/hda1 3.7G 1.8G 1.8G 50% /
/dev/hda3 13G 24K 13G 1% /cache
/dev/hda4 170G 105G 66G 62% /myth
Checked logs:
mythbackend.log and mythbackend.log.1 show no indication of a crash
syslog and messages also show no indication of it or mysql dying that I could notice.
However, the frontend comes back telling me it has lost connection to the backend, or the Watch Recordings list is empty and live tv just kicks back to the menus. If I stop and restart Mysql and the backend, it works again.
Nothing with the nVidia HW has changed, I have done nothing to the system is the last several months. What makes it odd is that it happens when no one is using it too. For example, the last item in the mythbackend.log was:


prior to that was the housekeeping thread at about 2:30


Now, there was a scheduled recording at 2:00 p.m. that is not reflected here, nor did it record. It is General Hospital and records every day. Except the last couple of days when the back-end died sometime during the morning/early afternoon. I can't tell when though to narrow it down. Any other ideas of where to look for what is happening?

UPDATE:
I did some more test while sitting here watching the logs.


This is interesting, it recorded for 1/2 hour, but the file is 0 bytes. Nothing. And because of this, the backend is trying to generate a preview, and cannot:


This machine has 3 PVR 250's.

LAST UPDATE


I set all three cards to record. cardid 1, 2, 3 after changing priorities of the cards. 2, and 3 are recording fine and the .nuv files are growing. However number 1 is not. OUCH. Has this card gone bad. However, I did set it to a priority of 0, the others are higher, so it is the one that is used for live tv, which does work. It seems like the backend cannot use it all of a sudden for recording though. This is new.

Hi;

"2005-08-12 18:02:12.310 Not enough video to make thumbnail"

I got the same stuff over here, latest release. For some .nuv
files it can generate .png files, for others this error (though
the .nuv looks fine).

Now if I remove all the .png files, some are regenerated,
some are not (see above).

But why? I've seen this problem in 3 postings now,
all since or later than aug2005, nowhere is an answer to
be found

in your case it sounds like the nuv file is fine. I take it the show was all there. unfortunately I think my card was bad. I hope to revisit that old card today, as I have set some time aside to upgrade, and do some work on it. There is another thread I started that has a similar issue, but I felt it was different enough to start a new one. http://mysettopbox.tv/phpBB2/viewtopic.php?t=6222 I have been reading about some thumbnail generation problems too, but they seem to all be related to unusable images. I think that problem is getting close to having a solution. I will report back, if I find any new info today.
