I am trying to adjust shared memory segments on a 32bit box:
| Code: | $uname -a
Linux home1 3.5.7-gentoo #1 SMP Sun Nov 11 15:21:31 CST 2012 i686 Intel(R) Pentium(R) 4 CPU 2.60GHz GenuineIntel GNU/Linux
|
So:
$ grep kernel.shm /etc/sysctl.conf
#kernel.shmall = 46869516
#kernel.shmall = 209715
#kernel.shmmax = 36869516
#kernel.shmmax = 536870912
#kernel.shmmni = 4096
kernel.shmall = 8388608
kernel.shmmax = 134217728
and then:
$ sudo sysctl -p
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.all.rp_filter = 1
kernel.shmall = 8388608
kernel.shmmax = 134217728
Ok great:
$ cat /proc/sys/kernel/shmall
8388608
$ cat /proc/sys/kernel/shmmax
134217728
But then why...
$ ipcs -lm
------ Shared Memory Limits --------
max number of segments = 4096
max seg size (kbytes) = 131072
max total shared memory (kbytes) = 33554432
min seg size (bytes) = 1
Apps behave like the values are those output by ipcs. I must be doing something fundamentally wrong... can someone straighten me out? |
