If you run with 128 MB shared memory, then the server should not use more then this memory, i.e. the depletion of memory you observed is not caused from OpenSER. The ammount of memory that is used from the server is: ((actual number of children) x private memory) + shared memory Perhaps you can adapt your "monitoring" to log the actual biggest memory consumer on the system?
