Symptoms

When a monitor description contains a \ (backslash) character, the system adds another backslash for every save-load operation. After enough saves/loads, the description eventually hits the maximum length, causing an error message: '01020057:3: The string with more than 65535 characters cannot be stored in a message' upon loading the config.

Impact

Configuration changes without human intervention. Potential load failure.

Conditions

Monitor with description containing backslash.

Don't use backslashes in monitor descriptions.

Fix Information
