Hi folks,

we have pretty much exhausted the topic of memory
allocation on Windows and Linux, but I don't remember
any discussion abut this on Mac OS.

So, I am using IDL 6.3 on Mac OS X 10.4.11.

I tried allocating as many 1GB array as possible,
and it failed after 3 successful allocations.
Now, the "Activity Monitor" indicates that at this point
I have 3.6 GB of memory used and 3.4 GB free.
So I am wondering why cant'I allocate a couple more
of 1GB arrays?

Cheers,
Paolo

IDL> c=bytarr(1000,1000,1000)
IDL> d=bytarr(1000,1000,1000)
