More memory required to compute statistics post test

I am receiving an error message saying that more memory is required to compute the post test execution statistics.

I was under the impression that memory management for the controller is now automatic. In the past I increased the xmx but I thought is was no longer necessary.

Actually the memory management is not automatic but it's a percentage of the RAM available on the machine whereas before it was the same value whatever your configuration.

For instance, if you use the local LG, it will be a quarter of your RAM and half of your RAM for a remote LG only installation. So with a 8GB machine, the localhost LG will use 2GB max and 4GB max with a remote LG.

You can still use the "-Xmx" parameter option to force a different memory settings for the controller in the <neoload_install_dir>\NeoLoadGUI.vmoptions file. Remove the option "-XX:MaxRAMFraction=4" from that file.

I couldn't see a -XX:MaxRAMFraction=4 in the file specified.

Have you already modified that file? I guess you are using a 5.xx version right?

If you look at the <install_dir>\conf\agent.properties. Do you see that option?

No I hadn't touched that file. I had increased the xmx in the NeoloadCmd.voptions - that's the only change. Yes using 5.0.2

It doesn't exist in the conf/agent.properties file either.

That's weird. So if you look at the modification date for these files, they have the same compared to the other installation files?

There are two sets of dates approximately a month apart in date modified.

I've just done a fresh 5.0.3 install and I see the RAM Fraction line now. When I delete this should I increase the -XX:MaxPermSize

Is this the same as the xmx value in previous versions?
