It is caused quite simply when the engine needs more memory and it decides to fetch itself some more :-)) To prevent them you need to add more mem initially. i.e. increase SHMVIRTSIZE. in your case you may want to try and set SHMVIRTSIZE = SHMVIRTSIZE + ( 4 * SHMADD ) Jo ___________________________________________________________________________ This email is confidential and intended solely for the use of the individual to whom it is addressed.
