Multiple 'System.OutOfMemoryException' errors in .NET 7 #78959

Description

@theolivenbaum

I'm seeing an issue very similar to this one when running a memory-heavy app on a linux container with memory limit >128GB RAM.

The app started throwing random OutOfMemoryException in many unexpected places since we migrated to net70, while under no memory pressure (usually with more than 30% free memory).

I can see the original issue was closed, but I'm not sure if it was fixed on the final net70 release or if the suggestion to set COMPlus_GCRegionRange=10700000000 is the expected workaround.
