Overnight EPG update causing Service to partly fail

[Lao Pan]

Since installing v5 18052020 there have been problems with the EPG overnight update

I have been getting the following Error in Windows log most nights and when doing a Manual update.

Yesterday I replaced the latest nshared & nutility dll's from https://forums.nextpvr.com/showthread.php?tid=60984 to see if that would help.
There was no overnight error, but on waking computer Kodi updated the listings, seems to play Live TV OK and record, but the tray icon is grey. Killing the process and restarting tray.exe does nothing - it required a service stop and restart to get the icon green again.

Logs are from immediately after kodi loaded listings and before attempting live tv etc.

Quick Kodi question - Have had a few problems where the schedules have been changed due to Covid 19 stuff, but the kodi epg has been scrambled. Looks as though the new programs / times were being added to the local Kodi cache, not replacing the previous ones.
I think I may have fixed it by disabling the [Use local epg cache] in Kodi - it is on the same machine as Npvr so only takes about 10 seconds longer to load Kodi on starting. Is this the correct solution?

Unfortunately the logs don't seem to quite go back as far as this. If you've got a c:\temp directory, do you have have a c:\temp\crash.mdmp file?

The kodi guys have been making changes around this area. I know they resolved it in most recent matrix builds, but I couldn't tell you want the story is with other Kodi versions.

Personally I would have local caching disabled if possible. They require it in most recent builds, but thankfully have fixed some of the performance issues with it.

Actually the expert on this, ksooo is recommending using local EPG only in Leia and earlier because the database method is broken. If you are not stopping and starting Kodi everyday then you are at the mercy of Kodi updating and it doesn't update the whole guide, if for example you sleep your PC.

Sub made an API change for me and I will be making the EPG update process more dynamic and it should handle EPG updates a little bit better (not including changes while Kodi is sleeping)

Looks as though this is the one for the 23rd 02:48 crash

Unfortunately that minidump doesn't really tell us much. It showed the process crashing in MSNP.ax, which is a microsoft tuning component. I can't really tell what it was doing at the time.

If it happens again try posting the logs again and I'll take another look.

Again tray icon grey, but Kodi seems to play OK - right clicking tray icon is very slow to respond
Logs for last night - there hasn't been a windows error or minidump since 23rd, but seem to be a  lot of inner exceptions in the nrecord log.

I have also noticed there is no device log for one of my tuners PCTV 292e - should it be using it during an epg update? - I'll give the pc a cold boot - it hasn't had one for a few weeks - sometimes need it for usb tuner recovery.

Can you exit the tray app and restart it?

Have to kill in task Manager then restart but still remains grey - until the service is stopped and restarted, then after about 20 seconds it turns green again and behaves its self.

I have just replaced nshared with the latest one from https://forums.nextpvr.com/showthread.ph...#pid541643 - hopefully the tray icon will survive tonight's update - it's been grey the last 3 mornings, just requiring a service restart to get going again. There have been no more overnight crashes of MSNP.ax.

Wife had a surprise after recording one of her programs a couple of days ago - as well as the one she wanted, there was an entry from July last year - no file though. It must have been a corrupted entry in the v4 db that came through the export / import of recorded programs to v5 that was now made visible by the updated nshared & nutility dll's.

Or maybe it was the program it's self - SUPERNATURAL

Replacing the nshared dll didn't help - icon grey again.
Yesterday there were 2 crashes of MSNP.ax Once at 09:18:28 and again at 23:45:17 - crash dump for this attached along with logs from this morning.
