If you are seeing some old and invalid objects in the “lotustraveler.nsf”, on the HCL Traveler server, try running “tell traveler cleanup show” command. It will show you which entries are obsolete and could be deleted.
Provided that you are OK with the result, run the “cleanup” command without the “show” option, this command will delete the entries previously shown.
To find out more about the HCL Traveler “cleanup” command, take a look at the official documentation.
