Crash Report - DHCP Leases - deleting expired results in error

I wanted to post here for (a) clarification on path forward, as I am seemingly unable to restart the DHCP service after multiple attempts, and (b) to advise those monitoring of the error as it sure seems like a product issue...

===========

Please advise. Thank you.

UPDATE:::

The above crash occurs when attempting to manually delete expired leases through the DHCP Leases GUI.

I really couldn't wait to hear back, so I took the corrective action of deleting the entirety of the DHCP.Leases file through:

Diagnostics, Edit File, Load "/var/dhcpd/var/db/dhcpd.leases", select all, delete. This got me back up and running.

The dhcp.leases file was ridiculously large for the small number of leases being allocated in my environment:

I looked over the php code in the /usr/local/www/status_dhcp_leases.php file and it definitely needs some attention/optimization.

jimp

The lease database size wouldn't normally reach that size... You might have a misbehaving client repeatedly making requests or otherwise causing trouble for the DHCP daemon.

You shouldn't need to manually delete or clean up leases either.
