# RETRANSMISSION.INBOUND.REQUEST_NOT_SENT

Advisory

## Subject Name Syntax

    _RV.INFO.SYSTEM.RETRANSMISSION.INBOUND.REQUEST_NOT_SENT

## Purpose

A receiving daemon produces this advisory when, as a chronically-lossy receiver, it censors its own retransmission requests.

## Remarks

A communications daemon presents this advisory to subscribing clients.

## Diagnosis

This advisory indicates that a receiving daemon’s retransmission control (RXC) feature has identified itself as a chronically-lossy receiver, and is protecting network bandwidth by censoring its retransmission requests (that is, not sending those requests). Each advisory corresponds to one censored request.

It is likely that the advisory DATALOSS`.INBOUND.BCAST` will accompany this advisory, since the receiving daemon does not request retransmission of the missed packets.

Check the receiver for the following possible problems:

| • | Some hardware component is experiencing intermittent failures; the component could be a faulty network card, a loose connection, or a frayed wire.

| • | A Rendezvous daemon process on the receiving host is starved for CPU cycles; either its host computer is too heavily loaded, or the priority of the daemon process is too low.

| • | The rate at which inbound data arrives overwhelms the capacity of the receiving host computer, which has insufficient CPU power, network bandwidth, memory, or some other limiting resource.

| • | If several hosts on the same network produce these advisories, the problem could be in the network routing or switching hardware.

## Message Fields

Field Name | Description
`host` | The IP address of the host computer where the chronically-lossy receiver (daemon) is running.
`lost` | The number of missed data packets for which RXC (in the receiving daemon) suppressed a retransmission request.
