public event OnPublishError PublishError | |
Event Data
The event handler receives an argument of type PublishErrorEventArgs containing data related to this event. The following PublishErrorEventArgs properties provide information specific to this event.
| Property | Description |
|---|---|
| SequenceNumber | Gets the sequence number for the message that could not be republished. |
| Status | Gets the status associated with the keep alive operation. |
| SubscriptionId | Gets the subscription with the message that could not be republished. |
Remarks
Exceptions in a publish response are not necessarily fatal and the Session will
attempt to recover by issuing Republish requests if missing messages are detected.
That said, timeout errors may be a symptom of a OperationTimeout that is too short
when compared to the shortest PublishingInterval/KeepAliveCount amount the current
Subscriptions. The OperationTimeout should be twice the minimum value for
PublishingInterval*KeepAliveCount.
