Dave,
<BR>Just a thought ... The cshell in Solaris imposes various limits on
the resources that child processes can
<BR>use, including the data size. In my shell the command "limit"
will show the current settings.

<BLOCKQUOTE TYPE=CITE>We're having some memory difficulties. The problem

<BR>swap space allocated, and have verified that it is used correctly.
No
<BR>matter what we do, IDL seems to have a maximum amount of memory it
will
<BR>give us, and then no more is to be had.
<P>The procedure is to simply allocate storage:
<BR>z1 = fltarr(1000,1000,20)
<BR>z2 = ...
<BR>until the out of memory error occurs. We monitor system memory and
swap
<BR>space used. There is nothing else running on the machine, and since
we
<BR>don't approach the 8GB limit of physical memory, swap space doesn't
seem
<BR>to come into play.
<P>The system specifics are:
<BR>SGI Onyx2
<BR>8 CPUs
<BR>8 GB memory
<BR>IDL 5.2 or 5.3 (identical results)
<P>Any ideas out there?
<P>Thanks in advance for your help.
