Oh! And the stopped server is the first of the list. I doesn't matter if it's the first started, it's always this one that stops. All servers are derived from a web profile
I also have an issue with starting and stopping the servers. I'm using the Web Port startup poller and frequently if I launch two servers at the same time, one of them starts correctly but Eclipse never notice and waits for the timeout. When stopping, it frequently fails to notice a server has stopped (using process terminated poller)
