Do you have MAXDSIZ set in your kernel?  And what about any limits?

e.g. I have options         MAXDSIZ=(1024UL*1024*1024)
and "limit memoryuse unlimited"

which is all my 1Gb  physical memory.  The default is a mere 512Mb.  You 
might need users to be limited to a bit less, but I don't have any of 
them :-)
