Detailed Description

A sample has been lost (never received).

The following events can lead to a SampleLost event:

• When the Presentation QoS is used with coherentAccess set to true and ResourceLimits Qos is active a sample lost can occur when all resources are consumed by incomplete transactions. In order to prevent deadlocks the the current transaction is dropped which causes a SampleLost event.

• When the DestinationOrder QoS is set to BY_SOURCE_TIMESTAMP It can happen that older data is inserted after newer data is already taken by the DataReader. In this case the older data is not inserted into the DataReader and a SampleLost is reported.
• When the networking service detects a gap between sequence numbers of incoming data it will report a SampleLost event

Parameters
