There is a MySQL postfix database and all postfix config are generally in /etc/postfix.
Most paths are stored in /etc/postfix/main.cf.

How do you increase the number of open files a user (CWP or system)?  Editing /etc/security/limit.conf and /etc/sysctl.conf and then # sysctl -p doesn't do it.

Did you try the sysctl method in this link?

Otherwise, check the databases for any clues.

I figured it out. Had to read through the comments, this one fixed it:
Edit the /etc/pam.d/system-auth, and add this entry:
session required /lib/security/$ISA/pam_limits.so

Thought as much. Thanks for the feedback. Hope it makes it to the core in CWP.

by editing account you can modify security limits.

check current connections:

    ulimit -n

To increase the limit, open file:

    nano /etc/security/limits.conf

add the following lines at the end:
* soft nofile 65535

* hard nofile 65535
