ShardingCatalogManager::withTransaction() is used internally by resharding to run multi-document transactions across config.chunks, config.collections, and config.reshardingOperations. ShardingCatalogManager::withTransaction() should probably automatically retry on transient transaction errors.
This issue has become more likely now that recipients are concurrent writers to the document in config.reshardingOperations when reporting their state changes to the coordinator.
