Change number of open files for opcuiwww

Hello,

Running OML 9.21 on Centos 6.8. We have soft and hard limits in /etc/security/limits.conf to 65000 for all users. However, opcuiwww.ldap shows a limit of 4096 (when looking at /proc/<pid>/limits). Is there a way to get opcuiwww.ldap to start up with a higher limit? '

Thanks for any input.

Bob
