[SCIRUN-USERS] malloc error in ShowField module

I was wondering if anyone could elucidate the following error for me:

While dealing with a cropped data set of dimension ~ 500 * 500 *70, I have been experiencing "malloc" errors from the ShowField module in my visualization network. More specifically, within the SCIRun environment the module fails with an "Unspecified Error", but the command line reflects the underlying cause:

scirun> *** malloc: vm_allocate(size=536870912) failed (error code=3)
*** malloc[933]: error: Can't allocate region

In my searches of the documentation, the only similar error that I encountered dealt with the 2GB limit of a 32 bit system. However, at the time of the error, the memory utilization of the SCIRun process is only 1GB, so this seems to be inapplicable.

If it is of any use, the specifics of my system are as follows:

My specific system is a dual processor G5 2GHz with 4 GB of ram. The same problem manifested itself when the system had 1 GB of ram, and on an identical system with 2GB of ram. The installation on all of these systems was done from binaries.

Thank you in advance,

Henry Kozachkov
