[INFO-109] Dhcp client not running - restarted

Hello Monkey74,

Thank you for reaching out to the community, is your appliance deployed in HA or standalone mode ?

Can you share the output of the following:

# ps aux | grep dhcp
# cat /var/log/selfmon.log
# cat /var/mdw-debug.log
# version 
# rpm -qa | grep dhcp
# cat /var/mdw/scripts/dhcpd

Vivek,

Thank you very much for your reply. Please see the output of the commands below:

Additionally, the below was gathered from one of the DHCP events. I believe this happened with the ISP so, not sure if the issue is on that side.

By any chance the eth7 interface was unplugged ? Or went down due to any power outage situation? How often it happens ?

Hi, Vivek,

No, the Ethernet was not unplugged nor had a power outage. In fact, 

It does not happened very often, I can recall two or three times in the last month or two.
