Hello Andrew,

Correct me if I am wrong but it seems your system isn't running with libisc-export1105:amd64 1:9.11.16+dfsg-3~ppa1 (?)

I am running the following packages from the PPA, please note that libisc-export1105 is required (that's
where the fix is located).

root@dhcpd1:/home/ubuntu# dpkg -l | grep ppa1
ii isc-dhcp-server 4.4.1-2.1ubuntu6~ppa1 amd64 ISC DHCP server for automatic IP address assignment
ii libirs-export161 1:9.11.16+dfsg-3~ppa1 amd64 Exported IRS Shared Library
ii libisc-export1105:amd64 1:9.11.16+dfsg-3~ppa1 amd64 Exported ISC Shared Library
ii libisccfg-export163 1:9.11.16+dfsg-3~ppa1 amd64 Exported ISC CFG Shared Library

I'll leave this running until I can reproduce the crash or assume that the fix
works.

Please let me know if you can reproduce with those packages.

Thanks,
