It is not uncommon to see test fails with:

Error. Agent communication error: java.net.SocketException: Connection reset by peer

and there can be a range of reasons for it. However in recent days I have been trying to track down cases where the agent process just disappears without a trace: no errors in the main agent log, no errors in the specific agent log. I find it hard to believe processes can just vanish silently this way so I'm wondering if jtreg is somehow losing the process output, or not gathering files that may have been created. We should be able to find something to help show what has gone wrong.
