Postfix CSF Excessive Resource Usage


Suddenly out of nowhere I have started receiving ‘Excessive resource usage’ emails from ConfigServer Security & Firewall in regards to Postfix. I have gotten emails in the past about excessive resource usage with other processes which I was able to know why but with Postfix, I’m not sure why in this case especially never receiving it before in regards to Postfix. This is the contents of the email:

Time:         Sun Sep 11 14:40:26 2022 -0400
Account:      postfix
Resource:     Process Time
Exceeded:     1834 > 1800 (seconds)
Executable:   /usr/libexec/postfix/proxymap
Command Line: proxymap -t unix -u
PID:          10107 (Parent PID:16260)
Killed:       No

Since it’s my first time receiving these emails in regards to Postfix, my concern is if this is some kind of security issue with Postfix or is this normal?

Thank you in advance!
