I’ve been having an issue with JMeter periodically pausing when running a load test and am not sure how to resolve this. We have tried several things, but nothing seems to be working. The behavior is I start a JMeter load test. The test will run fine for a few minutes, then pause, then pick back up, then pause, etc. I’ve tried upping the heap size when starting JMeter, running in distributed mode and non distributed mode, even turning off our Anti-Virus software, but the issue still persists. The amount of load being generated isn’t that much either. My test has about 75 different thread groups, but we are only using 1 thread per group. The last thing I tired was adding -XX:+DisableExplicitGC to jmeter.bat file, but that didn’t work either.
Does anyone have any other suggestions or thoughts? Do the logs reflect the delay? (or could it just be a delayed display issue) Do you have any data visualizations/listeners running during the tests? (they can eat up a lot of CPU cycles) Do you have anything else running on the computer that might be stealing the network card? Is there a pattern that might point you somewhere (like it happens nearly at the same test, or every 12.5 seconds or something)? No direct help, but those are all things that I have seen affect my tests. -Bob --- Bob Nance Novation Systems [email protected]<mailto:[email protected]> 256-534-4620
