====== Increase Service Timeout ======

Data Core consists of two windows services:

We've observed that the Intelligent Plant Data Core Service does not always reliably start following an ungraceful shutdown of a VM Host (i.e. a power cut).

The underlying cause is not fully understood, but we believe it is related to the high resource overhead of extra checks Windows performs following a dirty shutdown, resulting in a service start timeout. Moreover, windows service recovery options (which should attempt further restarts) do not trigger on a timeout.

If Data Core is performing a critical function in an environment with an unreliable power source, consider configuring an extended //service-timeout// to mitigate for this problem.
