I have some perl scripts running via CGI to print some monitoring informations out.
# cat /etc/redhat-release
CentOS release 6.10 (Final)
# getenforce
Enforcing
# LANG=C ausearch -m avc --start today
type=SYSCALL msg=audit(1547733474.941:28): arch=c000003e syscall=62 success=no exit=-13 a0=641 a1=0 a2=7f33500079b0 a3=31372f656d6f7268 items=0 ppid=1399 pid=1439 auid=4294967295 uid=48 gid=48 euid=48 suid=48 fsuid=48 egid=48 sgid=48 fsgid=48 tty=(none) ses=4294967295 comm="httpd" exe="/opt/rh/httpd24/root/usr/sbin/httpd" subj=system_u:system_r:httpd_t:s0 key=(null)

I see a lot of such entries but I don't see any service misbehaviour. All scripts are running fine.
Any hints how to classify this AVC; "Denied Signull"?
