jmeter hangs up and won't return

I am running 340 concurrent users to load test on server using jmeter.

But on most of the cases jmeter hangs up and won' t return, even if I try to close the connection it just hangs up. and eventually I have to close the application.

Any idea how to check what is holding the requests and how to check the requests sent by jmeter and find the bottleneck.

Got the following message on closing the thread

Solution

  • I've hit this several times over the past few years. In each of my cases (may not be in your's) the issue was with the Load Balance (F5) I was sending my traffic through. Basically a property called OneConnect was holding the connections in a time-wait state and never killing the connection.

    Run a pack tool like wireshark and see what's happening with the requests.
