DU Managers,
We have a memory problem running IDL apps. IDL support says
its got something to do with the OS, not IDL itself. We get
this memory error with all of our 3000/600s and 2100 servers.
The 2100 servers have 1Gb of memory and 3Gb of swap. This is
very puzzling because we can run the same program on lesser
VMS machines with no errors. I'm guessing there's some
paramter that can be set to avoid this. BTW, all of our
Alpha's run DU 3.2x. Here's the IDl error:
