mythpreviewgen does not run

[mythtv@…]

Mythpreviewgen does not run. Running stat against the binary shows that it does not get touched, so the backend does not appear to be calling it.

This means that if you try and delete recordings, you cannot as it comes back and says the preview is being generated. It's not...

Although auto expiring does work of live viewing, recording cannot be deleted.

This may result in disk space filling up.

Resetting defaults.

Are you sure your filesystem is actually configured to record access time, such that you would be able to track when it runs in that manner? Could you provide backend logs showing that mythpreviewgen is not being run?

You're right, the file system was not configured for access time... apologies.

I moved it to ...bin and created a shell script to call the bin file.

It calls with: --size 0x0 --chanid 9901 --starttime 20131129220658 --verbose general --logpath /var/log/mythtv --loglevel crit --quiet

However it segfaults.

In most mythpreviewgen logs (I should have looked at this before), has:
