But I haven't got the time yet to retest the same application / server with same client PC and there is still a slight possibility that it might be some other problem. I'll get back on these two threads when I do re-test.
Momentarily, I've checked if the connections started from jmeter are closed properly ( netstat -an -o -p TCP ). Both normal connection that ended properly or those that ended abruptly (by any inventive means) DO CLOSE after a short period of time. So it is definitely not a jvm / client-os problem. However, at the rate of the test, it is possible to run out available connections for a large number of threads - and that would be a test-environment issue (but it must be an exceptional case).
