Comment 1 John Mazzitelli 2014-08-01 17:05:42 UTC
well, I'm not convinced yet this is a problem. Why should the agent terminate immediately? In this case, it is waiting to finish doing what it was told to do (that is, restart EAP through the restart operation - the EAP restart hasn't finished yet, right?). I would rather the agent finish managing the production resource (that is, finish restarting the EAP instance) than have the management tool (the agent) immediately die and not finish. Or do I misunderstand the problem that is being reported?

The operation finished and marked as such in the UI, that's not the problem. Look at the attached file. We have two threads reading the output of a running process.
