When attempting to access messages from RDM for Motif window, and this error message displays, the problem is probably that there are more than 1000 messages in the RDM message window. This is a known bug and the workaround is to manually delete some messages via sql. If iview is not in the UNIX user's path that launched RDM, then help will not start.
Information scrolling area is incomplete based on windows size limitation.
The above error message shows up while bringing up rdm. It is because the vaults in rdm was exceeding the vault limit, which is set to 1000 at this point. Have less than 1000 vaults. The above error occurs when too many objects are marked for archive and the list becomes very long. Problem gets solved by narrowing the mark up list down.
