Large Arrays, and LOH Fragmentation. What is the accepted convention?

Question

I have an other active question HERE regarding some hopeless memory issues that possibly involve LOH Fragmentation among possibly other unknowns.

What my question no

Answer 1

The first thing that comes to mind is to split the array up into smaller ones, so they don't reach the memory needed for the GC to put in it the LOH. You could spit the arrays into smaller ones of say 10,000, and build an object which would know which array to look in based on the indexer you pass.

Now I haven't seen the code, but I would also question why you need an array that large. I would potentially look at refactoring the code so all of that information doesn't need to be stored in memory at once.
