QUEUE.SCHEDULER.OVERFLOW

Advisory

Subject Name Syntax

_RV.WARN.RVCM.QUEUE.SCHEDULER.OVERFLOW.name

Purpose

A distributed queue scheduler presents a SCHEDULER.OVERFLOW advisory when it discards a task because its backlog of tasks is too great and no workers are available to accept a task.

Remarks

The name element is the distributed queue correspondent name. The name may consist of several elements, so the wildcard character ">" (rather than "*") is the correct way to match all subjects in this position.

The scope of this advisory is the transport that created the scheduler member.

Notice that if the scheduler has not set its task backlog limit, then the queue can never overflow (and this advisory is never presented).
