We have a c# (3.5 framework) socket server which is a console app, after about 3000 connections (or less, it's quite random), we get an unhandled exception which crashes the app completely.

We're really struggling to find out what's happening and where, the only info we get is below, can anyone shed any light? It should be noted that EVERYTHING is wrapped up in try catch{}
