I have discovered that this new message has been appearing in the MUF log.
Is this message new with 15.0? Does the message imply that the LXX needs to be increased in size?
The DB00321I - LOG LXX WRAP message is a new enhancement for 15.0. It is issued each time the LXX wraps. This wrapping was always occurring but now we tell you when it happens. It is just informational and does not necessarily mean the LXX needs to be resized. However, the information in the message can help you to decide if it does need to be resized.
