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;

What do you get when you do:cat /proc/<PID OF ASTERISK>/limits ?

Strange. What's the output of:lsof -u <USER RUNNING ASTERISK> | 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
