ConnectionClosedException: Server closed connection without DISCONNECT.

[kenlee0305]

When i run my test plan with the number of threads exceeding 50, the test with the number of threads 51 starts getting the following exception. Does anyone know how to fix it?

Thank you

Try increasing the setting for number of open files by typing : ulimit -n 20000
