Allocation Error, Still have memory: Why?

[john3]

Under IVF 9.1, Win XP, PC with 2 GB hard memory, 3 GB VM.

When my codeis using about 1.65 GB (shown by task mgr for this process), I get an allocation error 41 when trying to allocate an array which should easily still fit in under the 2 GB limit.

Any ideas as why this happens and what can be done to fix problem.

Thanks.

If the memory allocator says insufficient memory, there's not much that can be done except move to a 64-bit system. I'm not sure that the task manager's view of process memory tells the whole story, and you don't get ALL of that 2GB - some is taken up with OS code and data structures. I generally find that 1.75GB is a practical limit.
