More than 95% of Java heap memory is being used warning.

Hey Mdar 

It all comes down to the spec of your machine, the size of the project (how many tests, teststeps and what the tests are doing), as well as what else you've got running on your machine which impacts whether you get close to your memory boundary.

There's things you can do within ReadyAPI, like setting to discarding successful results, not storing the test results in history db, disabling the logging of results, tweaking your vmoptions file, running in headless mode.

I actually stopped trying to run stuff like JMeter and SoapUI/ReadyAPI on I5's with anything less than 16Gigs about 5 years ago cos I kept hitting this problem.  I now run with I7 minimum 16Gigs and that seems to sort me for the most part.

Have a look at the following link - it'll show you how to tweak your setup to max out your capability.  The fallback option is run in headless mode, but I find that annoying when I'm building/debugging tests.

Mdar It's a know issue introduced in 3.40.0 which generates a false error message 

"More than 95% of the Java heap memory is being used. The test results may be impacted. It is recommended you increase the VM option -Xmx or -XX:MaxHeapSize in the file ReadyAPI.vmoptions."

A quick workaround is to set your Xms option to the same value as the Xmx so in your case:

-Xms8000m

-Xmx8000m

Sorry for the inconvenience, a patch version will be released shortly.
