   Agree it's not fatal and likely is not a good reson for next RC.. I could not find any other related log errors. This looks like some race condition  possibly in the new HA scheduler loop - my guts feeling tell me this is in the new "short-cirucuitt"  part of the loop after the main loop is completed(). Havnt' looked at the code but I recalled there was some late addition here and that looks like this might be the reason (but if it is,then except the warning, it should be harmless)
