checkstorage may abort an object check when it encounters a page linkage error (100032).
checkstorage continues to verify the object if a more recent version of the page eliminates the page linkage error, or if the number of page linkage errors is fewer than the configured maximum linkage error value.

See Reference Manual: Building Blocks > dbcc Stored Procedures.
Concurrent updates on objects that use APL indexes disrupt the page linkage because checkstorage may not be able to access the rest of the page chain
An index is dropped during the page linkage check
Running checkstorage in a quiet state should reduce (or eliminate) the transient errors that lead to an aborted index check. To eliminate transient faults, run checkverify immediately after running dbcc checkstorage.
