I'm still not precisely clear what's going on, it might help if you posted the actual schema and the deadlock message which lists the precise locks that deadlocked. Are any of the DML you mention on other tables on those tables with foreign key references to this one? It's impossible for two inserts on the same table to deadlock against each other so there must be more going on than what you've described. It's hard to help much without a complete picture. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com
