I tried vi /etc/sysctl.conf kernel.sem = 250 32000 100 256 But output of ipcs -l is still m18s24:~$ ipcs -l ------ Shared Memory Limits -------- max number of segments = 4096 max seg size (kbytes) = 32768 max total shared memory (kbytes) = 8388608 min seg size (bytes) = 1 ------ Semaphore Limits -------- max number of arrays = 128 max semaphores per array = 250 max semaphores system wide = 32000 max ops per semop call = 32 semaphore max value = 32767 ------ Messages: Limits -------- max queues system wide = 16 max size of message (bytes) = 8192 default max size of queue (bytes) = 16384 So it seems that i can't change the value. I only use a vserver of my isp. Is that a cause?
