At the beginning of this code in runCreateIndexesWithCoordinator, a collection lock is acquired in MODE_IX using AutoGetCollection. This also locks the database in MODE_IX, but this lock is not yielded before trying to relock the database with MODE_X. This results in a conversion of the database lock instead of a relock, potentially resulting in deadlock.
