Hi, ipcs -l tells me that the limit for number of semaphore arrays is 128 where each array can grow upto 250 semaphores...now my question is, can i have more than 128 semaphore arrays if i can live with lesser number of semaphores per array, the limit for system wide semaphore not exceeding?? another doubt is can i modify the /proc/sys/kernel/sem file for the same?? any help is valuable :) Thanks in advance.. -praveen. -- Kernelnewbies: Help each other learn about the Linux kernel.
