I can't remember my suggestion, but can I'll assume this is for the
C++ netCDF interface.

I can't tell from your description.  Does the crash happen just after
a netCDF file is opened?  Or do you have to read something from the
file before the crash?  Is the "Resource not available" error coming
from an Exception or is this printed out by your program?

Just guessing, but it might be a problem trying to allocate more
memory than is available, perhaps because the swap space is all used
up by something else.  But I have no idea what is allocating the
memory; it could be another process ...
