[further infos missing] Error: Mediaportal stopped working (1 Viewer)

[mylle]

Hi guys,

I dont think this is specific to 1.2 RC but while using mediaportal I every so often get a popup that mediaportal stopped working

I can actually just close the pop up box and mediaportal keeps running but its very annoying. I happens in Live TV and while watching movies.

Im getting this error in error.log

Nope.

As we keep telling you all, we need the full logs. All we know is what happened last. We have no way of knowing how it got to that point.

Please provide the full logs, or I will delete the thread as per our policy.

Hi Jacob

It is something to do with watched folders. Can you please turn on debug level logging. This will be caused by some specific folders or files, and debug logging should tell us which ones they are. Not that that is a solution - just trying to be practical.

Great. I will do that and wait for it to crash again.

Thanks alot!

try and disable the experimental "file existence patch". found in mp config under "GUI".

in short: it's a threading issue with this particular feature.
