"Clear all DHCP leases" button breaks ability to view DHCP leases
0%
Description
After doing a fresh install of pfsense 2.6.0 on top of Protectli Vault FW4B, everything seemed to be going well.
Then I was trying to make a static mapping for one of my devices. After adding it and restarting the DHCP server, I still saw the old IP getting used, instead of the one I mapped out.
So, I decided to try and hit "Clear all DHCP leases". Everything seemed to go fine.
However, afterwards, it shows 0 DHCP leases. I deleted my static entry and restarted. Still 0 (even though multiple devices are connected).
I tried that old IP that I was changing with my mapping - and the old leased IP for that device was still working. So, DHCP is working, but it's just not showing anything in Status -> DHCP Leases.
Furthermore, I now see these error messages in the associated logs:
dhclient 7753 Cannot open or create pidfile: No such file or director
There were none of these before I hit this button.
Any advice is most appreciated. Otherwise I'm just going to re-install from scratch and pray I never hit that button again.

- Status changed from New to Not a Bug
That action stops the daemon, removes the lease database, then starts it again. Entries are not automatically added back in until a client makes a DHCP request, which could take hours.
It's not a bug, it did exactly what it was told to do, and as clients eventually restart or renew their leases the data will start to repopulate.
