Certo, deve ser o suficiente para qualquer pessoa, definido como (ULONG_MAX - (1UL << 24))
. Observe, no entanto, que não é um processo por processo, mas um valor geral. Consulte o link :
* SHMMNI, SHMMAX and SHMALL are default upper limits which can be * modified by sysctl. The SHMMAX and SHMALL values have been chosen to * be as large possible without facilitating scenarios where userspace * causes overflows when adjusting the limits via operations of the form * "retrieve current limit; add X; update limit". It is therefore not * advised to make SHMMAX and SHMALL any larger. These limits are * suitable for both 32 and 64-bit systems.
