The ipcs -m command on the server report: ( anything )
------ Segm. Memoria Condivisa --------
chiave shmid proprietario perms byte nattch stato
the ipcs -lm command report:
------ Limiti della memoria condivisa --------
numero massimo di segmenti = 4096
dimensione max seg (kbyte) = 32768
max total shared memory (kbytes) = 8388608
dimensione min seg (byte) = 1
I need to setup something ?
Thanks,

These can be killed off using the unix ipcrm command. See the relevant unix man pages for details.
