When i run the script with small number of users/threads and via the CMD the run finishes smoothly (188) users

when i increased the users to 1000 with a ramp up of half an hour steady state for 1 hour and ramp down for half hour

the run crashed in the middle with a errorlevel=-1 , error from the CMD when it crashed things i've done : -Increased the Heap size to 18g as the machine has memory of 32g -iteration time is 1 min -think time 5 seconds

is there anything that can be edited in the jmeter configurations or this error is coming from the windows itself?

  • you should consider distributed testing. a standalone machine may lack resource to ramp up so many users. – Lei Yang Mar 30 '22 at 01:49

Your errorlevel=-1 doesn't tell anything to us apart from the fact that JMeter Java process has exited with non-zero exit status.

The reason most probably in jmeter.log file.

You can also check the presence of .hprof files in the folder where you launched JMeter from, if this is the case - it indicates that JMeter has encountered an OutOfMemoryError

With regards to edited in the jmeter configurations - just make sure to follow JMeter Best Practices and if you do already you should consider allocating another machine and running your test in Distributed Mode
