[Kea-users] DHCP4 Server crashes - Unable to read PID

Good morning all,

I have 3 instances of KEA running in HA on Ubuntu 24.04 LTS, so 6 servers total. This is the 2nd time now that I am running into the issue where my DHCP process will crash with this error message: DHCPSRV_MEMFILE_FAILED_TO_OPEN Could not open lease file: Unable to read PID from file '/var/lib/kea/dhcp4.leases.pid'

Has anyone else seen this or know how to fix it? The last time I just deleted the dhcp4.leases.pid file which worked on my standby server but shortly after I had the issue on my primary server and deleting the file there rendered my server unusable.

Any help would be greatly appreciated.
