JMeter crash while loadtesting / dumps html into jmeter.log
Hello,
While performing a loadtest on a website (10000 threads (each containing
18 requests) in 1 hour (3600 sec.)) we have noticed the JMeter GUI
slowed down severly. The PC it runs on performs well, just JMeter is not
responding quickly to userinteraction.
Q: Is JMeter capable of applying these amounts of load onto a webserver?
After a while JMeter crashes. In the jmeter.log there are quite a few
'java.io.IOException' messages and a few dumps of html, as seen in the
exerpt below.
Q: Is this a bug, or can JMeter 'legally' dump html into the log?

10000 threads is excessive.
18 requests - do you mean 18 separate HTTP Samplers?
And how many loops does each thread do?

Yes, Jmeter can put some HTML in the log file. This is to make it a
bit easier to determine the cause of webserver problems. In this case,
it seems you may have overloaded the server.
