I modified /etc/security/limits.conf,what I added is: "* soft nofile 81920 * hard nofile 81920" I also modified /etc/pam.d/login,that I added is: "session required pam_limits.so"

The output of "ulimit -a" is: core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 385898 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 81920 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) 385898 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited What I did is right?
