[New Scheduler] it's rarely happened but there may be an infinity loop in scheduler

[jiangpengcheng]

when queue is deleted from a scheduler in memory but its leader key still exist, msgs will be sent to the scheduler and sent to itself infinitely

logs are:

casued by below codes:

            case None =>
              logging.info(
                this,
                s"[${msg.activationId}] the key ${key} is not in the initRevisionMap. revision: ${msg.revision}")
              sendActivationByLeaderKey(key, msg)

it will consume logs of cpu resources and tons of info logs
