Bug reports seem to hint that the current default value of '1' is too low: the cluster is susceptible to scrub scheduling delays and issues stemming from local software/networking/hardware problems, even if affecting a very small number of OSDs. Squid will include a major overhaul of the way scrubs are counted in the cluster, providing a better solution to the problem. For now - modifying the default is an effective stop-gap measure.
