I keep getting this error erratically, i have confirmed that the relevant services are in fact running.
It kinda seems like some component elsewhere might be dragging down the host service, how do i go about troubleshooting this? Is there anyway i can maybe tweak this service to avoid this issue?
This is the error from the log:
