Crash in module mscorwks.dll while auto EPG update at 2:00AM

[hoborg]

Hi.
I noticed my EPG is missing in nPVR, so i went to LOG and found:

2013-03-06 02:03:40.624 [DEBUG][12] Async stop taking way too long
2013-03-06 02:03:40.624 [DEBUG][12] Stop() appeared to have failed. Exiting...

I think it is causing a .NET crash acording event viewer (LOG below)

In event viewer, i noticed two crashs apear nearly all days at 2:0x

If i run EPG update manually, there is no problem.

I am on Win7x64 and USB tuner Evolve mars (no problems at all with it).

Ideas?

Full log: (including texts from event viewer)

Hoburg,

See the other thread where there are more of us experiencing the same problems with Schedules Direct this past week:

I have heard it said that God invented war to teach geography to ...

But, then again, it could be related if there's some generic auto-update problem so perhaps I am being harsh ...

no, completely unrelated. hoborg has the graph stop crash that seems to plague people from time to time.

@hoborg, try unchecking the "use out-of-process digital recording" option. It seems that since that option was introduced, many have been more prone to problems when using the DVB EPG.

Thans for tip. I just disabled it, rebooted and did manual EPG update. Now lets wait few days and see.

Unfortunately I don't really have any suggestion for this one. A small number of people experience this, and I'm not sure what causes it.

This is non-critical and wont cause any problem, but is just saying that your DNS service couldn't resolve the name "www.gbpvr.com" when it went to check for new versions of the software.

Hi sub.
There is no way how to prevent this crash? Becouse it will stop the recording service.
Or at last popup message in nPVR that nRecord is not running? Or any other warning?

Hi sub.

I've never seen the problem myself, so haven't been able to run it up in the debugger to find out what is happening.

As a work around you can use an xmltv EPG source instead of DVB EPG.

Becouse it will stop the recording service.

Does the Recording Service only crash because of a problem with the EPG update from DVB?

Would it help to use the Windows Task Scheduler to run the a "shutdown /f /r" to force a reboot every night 15 minutes after the EPG update time?
