Symptoms

When you try to build an index (by using CREATE INDEX or ALTER INDEX) on a spatial data type of a large table, Microsoft SQL Server 2012 or SQL Server 2014 may perform poorly. You can find many spinlock contentions on SOS_CACHESTORE and SOS_SELIST_SIZED_SLOCK.

Note This issue typically occurs when there are many parallel spatial data operations.
