Hi, thank you for your reply.
@Pierre: MariaDB (in my case) handled deadlocks automaticly too. Good to known, I don't have to be worry about that. @Niphlod: I tried to beef up my database host. No effects. Another suggestion is to prevent the cases for such situation. I did it by an another extra code line in your worker function send_heartbeat: *if len(db.executesql(dead_workers_name)) > 0:* > db( > (st.assigned_worker_name.belongs(dead_workers_name)) & > (st.status == RUNNING) > ).update(assigned_worker_name='', status=QUEUED) > dead_workers.delete() > Erwn -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
