In Production, it randomly shows zero servers are active


What are some of the possible causes the hangfire server would stop working?

My app is on Windows Server 2008 R2 IIS server. 4.5.2 mvc app. with sql server for hangfire db

Is there a way to restart the server without restarting the app pool for the application?

Just noticed this happening over here too. For reference I am running it in dedicated (i.e. app server and dashboard are seperated) mode with selfhosted Owin windows services.

Odd thing is the app servers were still processing jobs so my guess would be a problem with the hartbeat mechanism or web pages for the server display.
