I looked through the code and are quite lost. There seem to be a 24 bit limit in ID + IDX bits (shmparam.h). Is this due to the fact that the other 8 bits are used for SWP_TYPE ? What is the limit for SHMMAX and what advantage is there to leave it at a lower limit ? What we need are many big shared segments (say 4000 * 1 GB). Is this possible with the current implementation ? Or what must be changed ? Only SHM_ID_BITS and SHMMAX ?
