NI: Error transferring to btexchange.box; Cannot  store document - database has too many unique f (4300922)

Error transferring to btexchange.box; Cannot store document - database has too many unique field names

Solution

This typically occurs due to abnormal growth of the btexchange.box over a period of time. One suggestion which has often worked in the past is to ensure regular maintenance is being performed on the database. Specifically the compact task. It is best to perform this maintenance offline and use a compact -c command.  If it is not possible to run regular maintenance offline using a copy style compact, then running a compact -B should allow for a compact while the system is still online. 

NOTE Please keep in mind routine Domino maintenance is strongly encouraged on all Binary Tree Domino Coexistence servers, databases and .boxes.
