Computer not sleeping

[robbyp]

Hi,

Its not going to sleep since the recent update of NPVR.

I've seen this before with previous versions and its been fixed. It just seemed to reappear again. I've rebooted etc and set the sleep timeout to 1 min to check.

powercfg is showing:

DISPLAY:
None.

SYSTEM:
[DRIVER] Legacy Kernel Caller

AWAYMODE:
None.

Even when no recording are going. Legacy kernel caller is keeping it awake. Since the computer had nothing but NPVR on it its most likely it.

Zip file included.

Maybe i should retro grade the program and see what happens, as its keeping the pc awake continuously.

I think you need to diagnose why this error is occurring during the EPG scan

I'd restart and do an EPG scan and see if those errors continue

Samething happened with my unit. 2nd time in about 1.5 years. I took the easy way out this time and reinstalled windows 10. works fine after.

I'm comparing and checking.

Have done lots of restarts.

Will check EPG redownload.

This PC is solely used for media playing so does not have anything else on it which can confuse the issue.

I'll report back when i have more conclusions - but this started with the 4.2.4 version

I;d also check the windows event viewer for app or system errors.

So, its started working again correctly..

As you said, there was an EPG error. I wonder if some data that was being broadcast in the EPG was crashing something. And now its gone from the EPG, its fine.

Will continue to monitor.

thanks

Seems I stumbled across another PC wont sleep type issue. A month ago or so I installed a fresh start version of Windows 10 on a PC and then put NPVR on it with an external USB tuner. Everything worked fine.

Yesterday evening I pulled out an Apple Ipad, turned on the chrome browser and went to the NPVR Web server on windows 10 home PC on my LAN to set up a recording and watch a few minutes of something else I had recorded. The recording set up went fine. However the attempt to play another recording kept failing when the display would say playing but nothing was playing. Anyhow I closed the tab, put away the seldom used IPAD and thought nothing more.

About an hour later I walked by the PC and noticed it had not gone to sleep. So I sat around a bit and noticed that it does go to sleep and after a count of about 7 seconds or so wakes up again and this cycle just keeps going. I checked "powercfg /lastwake" and it said the network/ethernet card was waking things up.

So figuring the only reason the network card is in the picture is because I used the IPAD to access it over the LAN I went to the NPVR settings panel, disabled the NPVR web server and sat around ten minutes. Result PC sleeps fine again.

This is actually the second occurence like this. The last time it happened -after much ado I figured I had messed up windows 10 and just reinstalled the OS and NPVR and the problem went away. This was a lucky break to catch that the web server is hanging somehow. The odd thing is that I could swear I accessed the web server in the prior month with an android device and had no sleep issues after.

But I do recall using the IPAD the first time this happened and before I decided to reinstall the OS.. is it possible the IPAD has something to do with causing the PC to keep the circuit open even when it is not being used? I am not a programmer just a guy that thinks he knows more than he does So I am passing this on to those that know better to ponder.

Its started again - not sleeping due to Kernal legacy caller, caused by a crash in the service I guess?

here is the log

Any ideas? NPVR is really unstable for me the last few months.

It looks like it encountered some issue extracting listing from one of your DVB frequencies.

Do you have a c:\temp\crash.mdmp file?
