Mythvideo metadata update downloading zero-length images

[myth@…]

I've recently updated to the 0.22-fixes branch and am trying to get my video collection sorted out. I'm using the "update metadata" option in MythVideo? rather than jamu, as I need to make sure the file naming is correct, etc. as I go along.

Unfortunately, after updating a number of videos (between 150 and 155 when I've counted), it stops working properly - the metadata seems to update fine but all images are zero length. I also start getting repeated "TFW: Taking a long time to flush.." errors in the backend log (every second or two).

If I continue updating, a few videos later I get an "Unable to connect to mythbackend" error message - this is only for one video though, it's quite happy again after that (though still creating zero length recordings). This also appears to cause in-process recordings to stop (I've seen this a couple of times but can't be certain of the correlation) - a new recording starts after a few seconds though.

The backend needs restarting in order to restore full functionality.

I've tracked this down to a bug in ThreadedFileWriter? (ticket #7501), so this ticket can be closed.

Thanks Robin, knew it was there but hadn't had a chance to hunt it down yet.
