In previous releases, this issue can cause clients to see the following error message:
Starting with this release, less memory should be used in this scenario.
When multiple ColumnStore threads or processes try to access a managed shared memory segment for the Extent Map concurrently, a read/write conflict can cause the processes to crash with a segmentation fault due to a race condition. ()
In previous releases, cpimport, PrimProc, and DMLProc were observed to crash in this scenario.
