LinuxQuestions.org - rebooting has no effect of ulimit

On my centos-6.1, I changed the /etc/security/limits.conf file and rebooted the system, however the number of processes didn't change!

check max user processes and nproc

Code:

# ulimit -a

core file size          (blocks, -c) 0

data seg size          (kbytes, -d) unlimited

scheduling priority            (-e) 0

file size              (blocks, -f) unlimited

pending signals                (-i) 516285

max locked memory      (kbytes, -l) unlimited

max memory size        (kbytes, -m) unlimited

open files                      (-n) 4096

pipe size            (512 bytes, -p) 8

POSIX message queues    (bytes, -q) 819200

real-time priority              (-r) 0

stack size              (kbytes, -s) unlimited

cpu time              (seconds, -t) unlimited

max user processes              (-u) 1024

virtual memory          (kbytes, -v) unlimited

file locks                      (-x) unlimited





# cat /etc/security/limits.conf

*  -  memlock    -1

*  -  stack      -1

*  -  nofile      4096

*  -  nproc      2048
