I am getting this error for any random request. If i ran test 1st time i am getting error for one png request. In next run same png request passed successfully and error is seen for some different request.

Answer 1

This reflects server side issues as you are getting connection reset error. If you are doing real load test, do it in NON GUI mode, GUI mode is for scripting.
