Internal error in Java extension

Hello everybody.

I want to regress dummy variables on Volume. I use codes which are shown below.

 ods graphics on;
proc reg data = Sampledata_02_mer_dumvar plots(maxpoints = none)=(CooksD RStudentByLeverage DFFITS DFBETAS);
	model adjusted_volume = TRD_EVENT_ROUNDED_1 TRD_EVENT_ROUNDED_2 TRD_EVENT_ROUNDED_3 TRD_EVENT_ROUNDED_4 TRD_EVENT_ROUNDED_5 TRD_EVENT_ROUNDED_6 TRD_EVENT_ROUNDED_7;
run;
 ods graphics off;

The log file is:

NOTE: Multiple concurrent threads will be used to summarize data.
ERROR: Internal error in Java extension NewDoubleArray().
ERROR: Java virtual machine exception. java.lang.OutOfMemoryError: Java heap space.
ERROR: Java virtual machine exception. java.lang.OutOfMemoryError: Java heap space.

What exactly is a problem?

How can I fix that?

Thanks in advance.

The out of memory part of the error makes me think the requested plots are too many/complex for the memory available. Try running the code without the plots or reduce to a single plot.

If the single plot works then a work around would be to request only one plot and run the proc multiple times with the PLOTS(only) to suppress the additional model outputs.
