As the message says, you have too many open connections. When you have multiple machines, you must either provision your postgres to be able to handle a full connection pool (max_overflow preferrably, pool_size at least) for each nginx worker for each machine, or have SQLA connect to a pgbouncer that will do the shared pooling for you. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
