Now, I do 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. I can not find connection refused error in /usr/local/apache/logs/error.log or /usr/local/apache/logs/access.log.
Test is HTTP GET, index.html("It's works") Apache MPM is worker and setting below:
<IfModule mpm_worker_module>
StartServers 8
MinSpareThreads 64
MaxSpareThreads 1024
ThreadsPerChild 64
MaxRequestWorkers 512
MaxConnectionsPerChild 0
jmeter problem? any apache setting problem?
jmeter exception below:

It's not a jmeter issue:
check components between jmeter and apache (firewall, load balancer, ddos protection ...)
check apache settings, to check this rampup slowly and see starting from which load you get those errors.
