Table Dependency in WCF

Jun 4 at 12:23 PM
I have a webservice created using WCF. It's a single instance for now. When it starts up I add all the table dependencies that I need, together with an instance of SignalR. I use SignalR to spread the different notifications I get and it all Works as I want. For some reason the table dependencies suddenly does the autocleanup out of nowhere. I don't undestand why and it can run for days without it happening. The service hasn't crashed, it still Works. I know this might be a weird setup, but it seems to Work fine apart from this. I haven't seen it happen when the system is in use. It has only happened outside workhours.
