shared memory problem

You kernel is not allowing the engine to create any more shared memory segments. Build a new kernel increasing all relevant shared memory parameters especially any that relate to the number of segments a process is permitted. For now increase SHMVIRTSIZE and SHMADD since it seems to be the number of segments that is the problem not the size of one. Art S.
