The Integration Service truncated message data while reading from queue <queue>:<queue manager> in destructive read mode.
The Integration Service read a WebSphere MQ message that exceeded the precision of the MESSAGE_DATA column in the MQSeries source definition. As a result, the Integration Service truncated the data. Because the session is running in destructive read mode, the session failed and the Integration Service did not delete the message from the source queue.
Increase the precision of the MESSAGE_DATA column in the MQSeries source definition.
