# DELIVERY.FAILED

Advisory

## Subject Name Syntax

    _RV.ERROR.RVCM.DELIVERY.FAILED.subject

## Purpose

A sender presents this advisory when the time limit of a message expires before all registered listeners have confirmed delivery.

## Remarks

The time limit is fixed by the CM send call.

The sender presents this advisory after Rendezvous software deletes the message from the sender’s ledger.

The `subject` element is the subject name of the certified message. The subject often consists of several elements, so the wildcard character `">"` (rather than `"*"`) is the correct way to match all subjects in this position.

## Message Fields

Field Name | Description
`subject` | The subject name of the certified message. It is identical to the `subject` element. This field has datatype `TIBRVMSG_STRING.`
`seqno` | The sequence number of the failed message. This field has datatype `TIBRVMSG_U64.`
`data` | The data portion of the failed message. This field has datatype `TIBRVMSG_MSG.`
`listener` | A `DELIVERY.FAILED` advisory can contain one or more fields named `listener`. Each `listener` field contains the name of a listener that did not confirm delivery. This field has datatype `TIBRVMSG_STRING.`

## Diagnosis

This advisory indicates an error, and reports unexpected and usually undesirable behavior.

`DELIVERY.FAILED` advisories can indicate any of several difficulties:

| • | The physical network is unreliable.

| • | One or more receiving programs have terminated or are unstable.

| • | The sending program is using a time-out value that is too low.

| • | The sending program explicitly marked the message as expired.
