Strange HDD access

Hi

I was trying to solve constant HDD led blinking issue and stared ProcessMonitor session profiling for file system access.

I was surprised that Serviio is trying to access file system every 5 seconds! Log is below:

It would be nice if that could be solved

Except this i have to say that Serviio is awesome job

It looks like it might be a folder permission problem.

this looks like some low level Java checks, which I have no control over

My guess is that some objects are serialized to/from XML that have no custom wrapper class and that why java is searching serialization details in file system. That is what is sometimes done in other languages/libraries.

Specifying a custom serialization wrapper class could solve the problem, but that is just a lucky guess (since I never wrote single line in java )
