MonetDB - Transaction aborted issue

All, We are getting below error while creating a table. In the current session no other bulk load has happened. CREATE TABLE IF NOT EXISTS "SCHEMA_NAME"."TABLE_NAME" AS SELECT * FROM " SCHEMA_NAME "."TABLE_NAME" WHERE 1=0; INSERT INTO "SCHEMA_NAME"."TABLE_NAME" SELECT * FROM "SCHEMA_NAME"."TABLE_NAME2"; ERROR = !COMMIT: transaction is aborted because of concurrency conflicts, will ROLLBACK instead ~ Also, is there a way to update multiple tables at the same time without above error? Is this due to concurrent insert? Any help here is much appreciated! Regards, Sreejith
