Over the weekend we had a segfault error that locked up the entire VM.

Background:

  *   Mysql backend on separate server
  *   ~300 leases total
  *   3 months of up time
  *   ~4 host reservations
  *   Using Flex ID to change client ID to option 82 identifier
  *   Using DDNS to strip bad hostname characters
  *   Sql connection wait timer set to 10000
  *   Dhcp socket type set to udp
     *   Was RAW when issue occurred.

Segfault error from journctl:

Feb 09 01:49:03 harpy kernel: kea-dhcp4[12641]: segfault at 10 ip 00007fabaad99918 sp 00007fff8ff4b690 error 4 in libkea-dhcp++.so.8.0.0[7fabaad39000+fc000]
