Only when SBN becomes active, it will be cleared. {{invalidateBlocks}} is populated during block report processing. I think no queues including {{invalidateBlocks}} should be populated in standby. was (Author: kihwal): Since {{ReplicationMonitor}} is not running on SBN, {{invalidateBlocks}} is not consumed.
