Bug ID: 56821
Summary: Stuck Threads
Product: JMeter
Version: 2.11
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: Main
Assignee: [email protected]
Reporter: [email protected]
Hi, i created a simple test plan plugin, which does:
@Override
public SampleResult runTest(JavaSamplerContext context) {
try {
Thread.currentThread().sleep(25);
} catch (InterruptedException e) {
// stuff to log
}
SampleResult sampleResult = new SampleResult();
sampleResult.setSampleLabel(Thread.currentThread().getName());
sampleResult.setResponseOK();
return sampleResult;
}
}
Very simple as you see, with Thread Group definitions:
- Number of threads = 1000;
- Rump-up-Period = 0;
- Loop-count = 2;
When i run this Test Plan, mostly performs well. As expected in Summary Report
i have 2000 samples. But sometimes, i only have 1998 samples and 1 thread that
never ends, even if i request Stop Test in Jmeter GUI. When that situation
happen i noticed this lines appears in jmeter log:
2014/08/06 17:35:37 INFO AWT-EventQueue-0 jmeter.gui.action.Start:
Stopping test
2014/08/06 17:35:37 INFO Thread-7 jmeter.threads.JMeterThread:
Stopping: Thread Group 1-834
2014/08/06 17:35:37 WARN Thread-7 jmeter.threads.JMeterThread:
Sampler is not Interruptible: Java Request
2014/08/06 17:35:42 WARN Thread-7 jmeter.threads.ThreadGroup:
Thread won't exit: Thread Group 1-834
I even tried to perform this test using jmeter-server in a linux based OS, with
same consequences. I already increased jmeter memory parameters with any sucess
and tried the exactly test plan in jmeter 2.10.
After all tests i have done, i m forced to concluded that this situation can be
some kind of jmeter bug.
Best regards,
Ricardo Silva.
