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 --- Sent update done message to failover-partner failover peer failover-partner: peer moves from recover to recover-done failover peer failover-partner: peer update completed. failover peer failover-partner: I move from recover to recover-done failover peer failover-partner: peer moves from recover-done to normal failover peer failover-partner: I move from recover-done to normal failover peer failover-partner: Both servers normal balancing pool 55d0a88a4f10 12 total 221 free 221 backup 0 lts -110 max-own (+/-)22 balanced pool 55d0a88a4f10 12 total 221 free 221 backup 0 lts -110 max-misbal 33 --- balanced pool 55eb2fe58f40 12 total 221 free 111 backup 110 lts 0 max-misbal 33 Sending updates to failover-partner. failover peer failover-partner: peer moves from recover-done to normal failover peer failover-partner: Both servers normal --- DHCPDISCOVER from 52:54:00:d1:eb:66 via ens4: load balance to peer failover-partner DHCPREQUEST for 10.19.101.120 (10.19.101.233) from 52:54:00:d1:eb:66 via ens4: lease owned by peer On failover: peer failover-partner: disconnected failover peer failover-partner: I move from normal to communications-interrupted DHCPDISCOVER from 52:54:00:e8:14:0a via ens4 DHCPOFFER on 10.19.101.10 to 52:54:00:e8:14:0a (shapely-peccary) via ens4 DHCPREQUEST for 10.19.101.10 (10.19.101.127) from 52:54:00:e8:14:0a (shapely-peccary) via ens4 DHCPACK on 10.19.101.10 to 52:54:00:e8:14:0a (shapely-peccary) via ens4 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.
