Apache studio seems to crash often both in the stand-alone version and the Eclipse Kepler plugin. The issue once it crashes is that I cannot reconnect using the port. It states that the port is already in use. This prevents the server from starting. Oddly, the connection will still work, but the server will not start and hence other issues start to arise. To sometimes solve this issue, and this does not always works, is to go to the servers folder and delete the .dirservice.lock
But this solution does not bode well, since the crashes still continue and eventually this option fails as well. I end up deleting the entire download and starting fresh.
