I think I have found the issue. I'm not sure if all of the following steps are
necessary to reproduce it but I will list my exact setup here:
- I have a storage group containing 2 hard drives.
- MythTV is set up to keep at least 10GB of free space on each disk
- I use one of those disks to put other stuff (Music, Videos etc) onto it
- I have some Recordings on this disk that are marked as "No autoexpire"
Now, if the disk fills up with other stuff and non-autoexpiring recordings to
more than the allowed quota, mythtv tries to find out what could be deleted
and seems to hang. Moving all of my non-autoexpiring recordings to the other
disk let the issue disappear.
@Adam: Do you have a similar situation producing your backend lockups?
Is anyone else experiencing similar problems and could confirm this behaviour?
