about Grinder MultiThreads

Hi  All

 

Sorry, I have queation about Grinder MultiThreads.

 

I write WriteMulitpleLittleFile Method test Java IO. I use Grinder Control test case run.

 

Appear Stack Overflow when start test. I set javatest.durationMinutes = 10 and grinder.threads = 1 in properties file.

 

I'm not sure this problem. I don’t know how to Control Grinder test threads in test code?

 

Please you help check.!

 

Thanks!

Attempting to allocate 512M bytes

 

There is insufficient native memory for the Java

Runtime Environment to continue.

 

Possible reasons:

  The system is out of physical RAM or swap space

  In 32 bit mode, the process size limit was hit

 

Possible solutions:

  Reduce memory load on the system

  Increase physical memory or swap space

  Check if swap backing store is full

  Use 64 bit Java on a 64 bit OS

  Decrease Java heap size (-Xmx/-Xms)

  Decrease number of Java threads

  Decrease Java thread stack sizes (-Xss)

  Disable compressed references (-XXcompressedRefs=false)
