There are consistent failures in the concurrency_sharded_multi_stmt_txn_with_stepdowns and concurrency_sharded_with_stepdowns suites as a result of slowness in the checkMetadataConsistency hook. Each checkMetadataConsistency command was taking 7-8 seconds causing the moveChunk operations to start every 7-8s and subsequently fail with an interruptedDueToReplStateChange error. This error is to be expected since the stepdown hook threads runs every 8s. Increase the stepdown thread interval in these suites to avoid the moveChunks from consistently hitting the interrupted error.
