NextPVR Forums

Hi,
I'm seeing intermittent (about once a week) crashes of NextPVR when recording. Last night it was scheduled to record a show at 3am, finishing just after 4. When I woke up there were a couple of Windows crash log dialogs on screen. In the Windows event log, I can see the following at 2.59:
[INDENT]
Faulting application name: NDigitalHost.exe, version: 1.0.0.0, time stamp: 0x57eb372e
Faulting module name: clr.dll, version: 4.6.1085.0, time stamp: 0x57a4fc7a

Then there are two entries at 4.08:

The odd thing is that the recording in question seems to have completed OK, but I had to restart the NPVR services this morning.

Please find attached the NPVR log as requested.

Could someone please take a look and see what's causing this, as currently it means I can't leave NPVR reliably recording things over a period away from my computer.

Thanks
Andrew

Create a c:\temp directory, and next time it happens, check for a c:\temp\crash.mdmp, and supply that file. This will give me some debug info on why it crashed.

The "removing filter ..." lines then repeat a zillion times.

Results are often unpredictable if the EPG update overlaps with a recording. You should get a smooth result if you ensure that overnight recordings don't overlap with the EPG update.
