Apache httpd connection refused during stress test using jmeter -


now, stress test using jemter in windows(jmeter.bat). 

number of threads = 100 ramp-up period = 0  loop count = 1000

but raise connection refused error in jmeter, after 20~30 seconds. can not find connection refused error in /usr/local/apache/logs/error.log or /usr/local/apache/logs/access.log.

test http get, index.html("it's works") apache mpm worker , setting below:

<ifmodule mpm_worker_module> startservers            8 minsparethreads         64 maxsparethreads        1024  threadsperchild         64 maxrequestworkers       512 maxconnectionsperchild   0

jmeter problem? apache setting problem?

jmeter exception below:

it's not jmeter issue:

  • check components between jmeter , apache (firewall, load balancer, ddos protection ...)

  • check apache settings, check rampup , see starting load errors.
