Centos 5.9 I have set the below in /etc/security/limits.conf but when mMonit starts my processes the ulimit is still 1024. If I do ulimit -a it correctly shows 500000 as max open files. In /etc/sysctl.conf I have fs.file-max = 512000. Also root is the use that Monit is using to start the processes. I have rebooted and have the same issue.
* hard nofile 500000 * soft nofile 500000 root hard nofile 500000 root soft nofile 500000 * - nofile 655350
If I look at the process that Monit is managing I get:
[root@server1 ~]# cat /proc/8940/limits Limit Soft Limit Hard Limit Units Max cpu time unlimited unlimited seconds Max file size unlimited unlimited bytes Max data size unlimited unlimited bytes Max stack size 10485760 unlimited bytes Max core file size 0 unlimited bytes Max resident set unlimited unlimited bytes Max processes 257124 257124 processes Max open files 1024 1024 files Max locked memory 32768 32768 bytes Max address space unlimited unlimited bytes Max file locks unlimited unlimited locks Max pending signals 257124 257124 signals Max msgqueue size 819200 819200 bytes Max nice priority 0 0 Max realtime priority 0 0
