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
