Subject Re: [users@httpd] Thruk reports /var/tmp/live.sock: No such file or directory inspite of the file being present
Date Fri, 25 Nov 2016 18:40:46 GMT
may be worth checking with namei command to see the permissions are correct
for the whole path not just the end socket file.

namei -mx /var/tmp/live.sock
or
namei -mol  /var/tmp/live.sock

Also what does the httpd error log say?
