Test limiting memory with something like:

= SYS(3050, 1, VAL(SYS(3050, 1, 0)) / 3)
= SYS(3050, 2, VAL(SYS(3050, 2, 0)) / 3)

or specific:

=SYS(3050, 1, 512*1024*1024)
=SYS(3050, 2, 512*1024*1024)

see: http://msdn.microsoft.com/en-us/library/z5z3a4y8%28v=vs.80%29.aspx

and after a command that does a lot of processing:

= SYS(1104)
