I'm using 32bit Amazon Linux (Centos?). Per the blog http://gnufreakz.wordpress.com/2009/08/12/increase-ulimit-in-centos/ I tried changing some parameters.
I added the below line to /etc/sysctl.conf
fs.file-max = 65536
and ran sysctl -p
I added the below line to /etc/security/limits.conf
* hard nofile 65536
No luck! After a restart, ulimit -a still gives me:
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 26597
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 1024
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
Try adding
ulimit -n 65536
to your /etc/profile or to /home/[username]/.bash_profile
