CLIENT.FASTPRODUCER

Advisory

Subject Name Syntax

_RV.WARN.SYSTEM.CLIENT.FASTPRODUCER

Purpose

A sending client of the Rendezvous daemon receives this advisory when it produces data faster than the network can distribute it.

Remarks

Only the specific client transport receives this advisory.

This message is a warning—the program is sending messages faster than the physical network can accept them; the program’s outbound message queue will grow until it exhausts available storage. (In contrast to CLIENT.SLOWCONSUMER, this advisory does not indicate an error, because data is never discarded.)

When a client program sends many outbound messages in rapid succession, they remain in the client’s storage until rvd can accept them to place them on the network. When rvd leaves an outbound message waiting in the client program more than 5 seconds, Rendezvous software presents this advisory to the client transport.

This advisory does not occur when using IPM.

Message Fields

Field Name	Description
waiting	The number of outbound messages waiting in the client program.

Diagnosis

FASTPRODUCER advisories can indicate any of several situations:

•

The client program is sending messages in a tight loop—either the daemon or the physical network cannot absorb the volume.

•

The Rendezvous daemon is starved for CPU cycles; either its host computer is too heavily loaded, or the priority of the daemon process is too low.
