Jmeter buffer space

Question

I'm using J-meter to run some load scenarios on a web-service.

I'm sending a request with seventy five concurrent users for thirty minutes but after about five minutes I got this error:

java.net.SocketException: No buffer space available (maximum connections reached?): JVM_Bind

If you're running JMeter on Windows Server 2008 R2 or Windows 7 you should apply KB2577795 HotFix

If you're running JMeter on Linux, add the following line to /etc/security/limits.conf:

foo soft nofile 4096
foo hard nofile 65536

Where foo should be your Linux username

Also set a hard limit by running the next command:

ulimit -n 8192

Also check out the following references:

Beside this potential duplicate:

java.net.SocketException: No buffer space available (maximum connections reached?): JVM_Bind

Uou should not use SoapSampler anymore.

Read this for up to date way to test Soap WS:

https://jmeter.apache.org/usermanual/build-ws-test-plan.html

Besides, ensure you use last JMeter version.

What error do you get ? Are you sure the changes have been applied ? Can you describe what you changed ? – UBIK LOAD PACK Aug 11 '16 at 11:35
I deployed the new hot fix for windowse server 2008 R2, Increase heap size to the maximum available, increasing the number of max TCP/IP connections, increasing the number of MaxUserPort and decrease the number of concurrent requests – Ahmed Selim Nov 08 '16 at 09:09
