Hi,

We are using Redhat Linux and we are doing load test using apache JMeter (HTTPSampler) of our Web server (running in hp-ux). After few iterations, the jmeter thread hangs and we see the TCP Socket is left open and is in ESTABLISHED state. The ESTABLISHED state remains till the JMeter is shutdown. After it is shutdown, the socket state changes from ESTABLISHED to FIN_WAIT_1 and eventually cleans up after fews seconds.

Please help us to fix this problem as this is very critical and it is stopping us from doing the load test as the jmeter threads getting hanged and never completes the test successfully.

This problem does not happen if we use 250 threads and it is reproducible everytime with 500 or more threads.

Thanks in advance for you help.

Check if it's a configuration problem, a network problem, a problem in the application you're testing. If that all ain't it, make sure you test with logging enabled and get it to dump thread info. Read the mailing list archives for clues else dumping your info on the jmeter-user[at]jakarta.apache.org mailing list would be best I think.

Since it closes this doesn't seem a problem, doesn't it?
