Description
IndexCatalogImpl::_doesSpecConflictWithExisting() throws an exception if an index with conflicting options is attempted to be created while in FCV 4.4. However, a node undergoing initial sync will also call that function and (depending on whether the admin.system.version collection has already been cloned) would fail its initial sync attempt and eventually exhaust its retries.
