Connection Reset Error

Hello,

For the past few weeks, I have received this server error - http://i81.photobucket.com/albums/j2...ctionReset.png

I have a VPS rented, and use it to host a video game server. Every know and then, this error will appear. Sometimes it appears when it causes a client to crash. ( Client's Fault?) When this happens, the server still continues to run smoothly. At other times, the error will appear and it will make it seem like the server has crashed. Everyone becomes disconnected, but the server continues to run. When I check console, I see the error just repeating every few seconds or minutes and nothing in the server happens. Its like it just hangs there until I kill the process and start it over. Could these be an error with java or perhaps a port?

If anybody has any ideas, please let me know. Any help is more than appreciated and I would love it if My server ran 24/7, without this error causing it to go down until I start process back up.

Thanks,
Kfperin
