DXSHMEM if set to 0 forces shared memory to be used. I could import those smaller netCDF files (at www.SciSpy.com/FTP/netCDF/) without any problems.
Your 16 MB file fails on a 1 GB machine with -memory 750 fails. So (even) if you do increase DXMEMORY it will likely fail. I guess if someone else wants to try on another system, the files we are talkingabout are at: ftp://maelstrom.deas.harvard.edu/pub/leslie/DAMUS and pe_out_rr97.nc is the 16 MB file we have been talking about. I guess I do not know enought about the data you are trying to import to say what the problem is. Does the netCDF file compactly contain a large grid of data that consumes lots of memory in the DX data model? Remember yesterday that on an IBM workstation, the error message said 369 MB were required. I do not know why the same error message does not come up on an SGI. Is the 9 MB file you successfully imported from the same source?
