Pi Song commented on PIG-99:
----------------------------

I run Pig in VMWare virtual machine Ubuntu 512MB memory JDK5 with default build.xml. Never
came across this before. Could you please give us more detail about your system?

> Proposed patch, add this to the junit tag:
> {code:xml}<jvmarg value="-Xmx512m  -XX:PermSize=128m -XX:MaxPermSize=512m"/>{code}
> or
> {code:xml}
> <jvmarg value="-Xmx512m"/>
> <jvmarg value="-XX:PermSize=128m"/>
> <jvmarg value="-XX:MaxPermSize=512m"/>
> {code}
> not sure which one is correct, I need to check...
> See [JUnit task|http://ant.apache.org/manual/OptionalTasks/junit.html] for more details
> An *even better solution* is to check why there is a OutOfMemoryError in the first place.
> May be it's a sign somethings'wrong or consuming too much memory...
