  We have a online examination application developed in ASP.net with SQL as backend database. The server is located at factory in Walchandnagar, connected through 2*2 mbps links. Total 200 users at a time attempted the exam from pune location. We had tested the exam for 5-10 peoples and found no problem, but the live exam failed. No n/w problem was observed. The errors generated at the live exam are attached here with. Please help us to find the reasons of the failure. We have the source code if required we can send you that.
