Normal operation does not "fill buffers", thus they don't need any flushing. There must be something weird about what your SP is doing. Can we see it? Are you maybe opening and keeping half-scanned a lot of cursors? If not, can you explain in much detail what it is doing? Alvaro, The stored procedures are long and complicated with recursive routines and temporary tables and deal with a lot of data. What ended up happening is that we added another very large chuck of data to the processing and that gave us the memory error. After looking closer at the error we upped the max_locks_per_transaction parameter to 256 and then we were able to execute without an error. Thanks for your help. Andy Nykolyn Northrop Grumman
