Cause
As a normal part of the operations in the server, stands are sometimes marked obsolete so they can be deleted later. For example, if stands are merged into a new stand, the old stands are marked obsolete. Typically, these stands will be deleted within seconds or minutes but, if there are long-running transactions or other activities like backups still using obsolete stands, they cannot be deleted until those processes complete. If obsolete stands are not deleted within an hour, the server will log this message for informational purposes.
Response
If the system has long-running transactions that are expected or backups that take more than an hour, these messages can be ignored. If not, these messages could be a reflection of other problems in the system and they can be used to help diagnose when unexpected long-running processes may have started to occur.
