We thought it best to leave the upstream > site unchanged while upgrading the downstream sites. LDM 6 was designed so that the upstream or downstream LDM-s could be independently upgraded. It doesn't matter which one is first; except that the downstream LDM-s won't see any advantage until the upstream LDM is upgraded. > When one of the downstream sites upgraded they encountered some > unexpected log messages.

The notice about the LDM version can be safely ignored; the other messages are more serious, however. > BTW, if there is a more appropriate target of opportunity than > yourself for LDM questions, please don't hesitate to adjust my aim > toward them!

This shouldn't happen. Was the previously-running LDM 6 properly shut-down (there should be some entries in the logfile indicating as much)? > > Not exactly sure what the above messages mean.
