Hi Subbu,

Vaguely rings a bell. From years ago.

Try the command "limit" in tcsh or csh (I think it's ulimit in bash, don't use bash myself).
[Mac OS X is a Unix system (BSD) so it should be similar if not identical].

I get here on a Linux box:

limit (followed by carriage return)
cputime      unlimited
filesize     unlimited
datasize     unlimited
stacksize    unlimited
coredumpsize 0 kbytes
memoryuse    unlimited
vmemoryuse   unlimited
descriptors  1024
memorylocked 32 kbytes
maxproc      32736

and make sure that memoryuse is unlimited

You add a line in your .cshrc or .tcshrc file:

limit memoryuse unlimited

Of course this will apply if the problem is due to your system not allocating 
enough
memory for the process.
If it's something else, I wouldn't know.

HTH,

Fred.
