lfd n myhostname: Excessive resource usage: apache

Hello,

1.1G /var/qmail/queue

When i cat some mail file:

cat 25465417
Received: (qmail 23595 invoked by alias); 21 Oct 2013 08:07:27 -0000
Delivered-To: root@myhostname

Please any ideas on what to do? It appears LFD is producing alot of mails..

 

I think these emails are sent based on COnfig server firewall setting located in /etc/csf/csf.conf

"
# This User Process Tracking option sends an alert if any linux user process
# exceeds the time usage set (seconds). To ignore specific processes or users
# use csf.pignore
#
# Set to 0 to disable this feature
PT_USERTIME = "1800"
"

and settings around it.

Question is why that PHP process is running 23 hours?
Im having just normal websites.
