Hi all,

Now a days getting openfile issues on asterisk quite often even setting system soft limit to 20000 and hard limit to 25000 and issue usually occurs during openfile socket consumed by system and asterisk is quite smaller than the soft or hard limit. See below system and asterisk logs;

Further added, I’m using CentOS 6.5 as OS.

Please advise what changes required for permanently fixing this random issue.

  • Strange. What’s the output of:
    lsof -u | wc -l

    I know that on some CentOS7 setups we needed to remove the file 90-nproc.conf as well as add to the Asterisk init script:
    ulimit -s unlimited ulimit -n 65535
    ulimit -Hn 65535
    ulimit -u 65535
    ulimit -Hu 65535

  • 50771 is the PID. I am talking about the user. for instances if running as root (which you should never do) then:
    lsof -u root | wc -l
