I don't really know how to explain the issue. Randomly whilst playing on the server (run and accessed by my computer), the server would spontaneously close. Usually, in game, the text on the kick-screen just says "Server Closed", even though I didn't touch it. Occasionally, it says it was shut down by a remote host. I apologize for my ignorance.
For all but 1 crash report today, the AMdescription is Watching ServerJava.lang.error.
It could very well be my anitvirus software (Norton 360), but I am skeptical of this.

one file attached is what most of the crash reports today look like, with the description as stated above. The other is the unique report that occurred (14w33a) while trying to launch the server on one try.

Thank you for your work!
