[mythtvnz] 0.21 upgrade has me losing recordings!

[Jason Haar]

Hi there

Two days ago I upgraded from 0.20 to 0.21 on my CentOS5 backend and my 
FC8 and minimyth frontends (the exact version will be slightly different 
- but all 0.21). For the first couple of hours it all looked great, I 
watched something and a recording auto-kicked in as expected. Life was good.

However, some time after that, the auto-recording function died. It 
stopped recording shows it has been set to record for ages. Because of 
this, several shows failed to be recorded when they should. And yet at 
the same time the playback feature was fine. Last night we watched a 
movie recorded a couple of weeks ago just fine - we just didn't notice 
it wasn't recording anything new.

So tonight  we noticed both mythfrontend and mythweb stated we had no 
"Recording Schedules" set. Argh! WAF hit 0% - years of settings lost! 
End of the world is nigh!

I checked /var/log/mythtv/mythbackend.log, and the only error I can see is:

RemoteFile::openSocket(file data socket): Could not connect to server "" 
@ port -1
RemoteFile::openSocket(file data socket): Could not connect to server "" 
@ port -1
RingBuffer::RingBuffer(): Failed to open remote file ()

The weird thing is, I simply restarted mythbackend and all the recording 
settings came back! They weren't lost after all - just "misplaced". I'm 
still seeing the above errors - but now everything looks fine - so I 
don't think they are related. I thought they might be related to the 
mysqld database - but that hasn't been restarted since last reboot - so 
it's not like it lost access. So the problem is that somehow mythtv 
loses it's references to recording schedules and stops recording new 
shows - and a restart allows mythtv to relearn them. However, as all 
this happened after I rebooted the backend (as I also upgraded the 
kernel and ivtv drivers when I upgraded mythtv), I guarantee this will 
be happening again unless I get to the bottom of this.

Any ideas what's going on? The CentOS5 backend is mythtv-0.21-183.el5. 
Thanks
