cf8 - memory issue when running process - java.lang.OutOfMemoryError: Java heap space

[SilentBob_secretfusion]

Hi, I am running code in coldfusion 7 generally without issue.  I am now running it in coldfusion 8 and am getting the below java issue.

Can anyone make any suggestions as to what might be wrong?  Thanks.

This should be related to your code. Generally heap space issue occurs if the code goes to infinite loop or is handling large data and the system RAM is very low.

The box has a 7.9 gigs of memory. It is not an infinite loop, however a good deal of data being processed.

I think I need to increase the heap amount, however I cannot determine how to do this.  Someone told me to increase this in coldfusion 8 adminstrator, however I don't see any java/jvm setting under Server Settings.  It is the enterprise addition.

Any ideas?

Thanks.

[Prasanth_Kumar_S]

I'm not sure about the enterprise edition settings and the Windows server settings. It should be the settings on OS that is restricting this option. Otherwise, if you are not logged in to CF administrator as admin, it is the user privilege settings. If it is allowed, you should see the option "Java and JVM" -> "Maximum JVM Heap Size (MB)" and increase the limit.
