Notes Error: B-tree structure in invalid

I have some code that does a db.Search of a db and takes the collection and dumps it in a SPOFU folder. Some users are getting the error message “Notes Error: B-tree structure in invalid (ExportContact)” ExportContact is the SPOFU folder name. The folder has about 60 columns and they are sortable… Any suggetions besides making the views non-sortable?

Are you deleting and recreating the folder in your code, or simply dumping the contents into the pre-existing folder?

The folder is already created. I am just dumping over 10,000 docs in the folder

That shouldn’t be a problem. You may want to do a quick cut/paste of the folder design note to force Domino to trash the old index, folder update list, etc.
