800xA 5.1 RevA Virtual System - AFW service restarts on all server nodes.
We have created a virtual system 800xA 5.1 RevA with images of production system and it has a weird problem that all the afw services shows it gets restarted and it is sporadic in nature.
But the system is on simulation all the history data and simulated operation works good.
We did all basic checks on network, domain and 800xa system. We have created more virtual system on a similar hardware running VMWare ESXi 5.1 with images of production machines and all of them running good for more a year.
Upon further investigation using afwapplogviewer we found,

Any valuable suggestion would be appreciated.

Can you upload a copy of the [Workplace Structure]Web System Workplace:System Event List?
One potential problem I'm aware of is that the system may become unstable if one or more of the services in the Service Structure continuously restart over a prolonged period of time, e.g. an OPC DA Connector or Event Collector desperately trying to connect a not available OPC server. Such service providers should be either disabled or deleted from the system.
