It's (Updated) ESXi-5.0.0-469512
Haven't chcecked Windows logs yet.
Yesterday I noticed VMware VirtualCenter Server not running so, pushed it manually. It died out again so, I gave the whole server a restart. Today it was running in the morning, but now when I look at it it's stopped again (it's set to start automatically(delayed start) of course. Just now I started it again and whe I try to connect vSphere to it I get a different looking window with similar error:
Connection Error
The request failed because of a connection failure. (Unable to connect to the remote server)
Call "ServiceDirectory.QueryServiceEndpointList" for object "ServiceDirectory" on vCenter Server "10.1.0.111" failed.
And only option is CLOSE.
Will start digging in the windows logs now.
UPDATE:
Call "ServiceInstance.RetrieveContent" for object "ServiceInstance" on Server "10.1.0.111" failed.
After refreshing SERVICES snap-in I see that vCenter Server service died again. ILooks like this is the problem. How do I diagnose it form here?
Inventory service, Managment Webservices are running.
VMware vSphere Profile-Driven Storage Service keeps dying too, even though it's set to start automatically.
vCenter Server service stops everytime I tried to connect vSphere to it.
UPDATE2: after manually starting the service I am able to login to the WebClient, but I only get the genral layout and all the content is not being displayed. Got some "java exception: connection reset" too.
