hearbeat vip disappear upgrade packages

[Andy Magnoux]

Release of Ubuntu :
Description: Ubuntu 18.04.3 LTS
Release: 18.04

Version of package :
* heartbeat:
  Installed: 1:3.0.6-7
  Candidate: 1:3.0.6-7
  Version table:
 *** 1:3.0.6-7 500
        500 http://fr.archive.ubuntu.com/ubuntu bionic/main amd64 Packages
        100 /var/lib/dpkg/status

It happens since multiple versions.

Example of Configurations Files we use :
* Haresources :
node1 IPaddr2::10.00.00.100/24/ens160

* ha.cf :
use_logd on
udpport 695
keepalive 2
warntime 15
deadtime 30
initdead 30
mcast ens160 239.0.0.43 695 1 0
node node1 node2
auto_failback on

* authkeys :
auth 3
3 md5 passphrasesforauthentication

I expect to keep the vip on the interface when I upgrade, but when I upgrade the following packages on different VMs I loose the VIP and the bakcup doesn't keep the VIP too until I restart the heartbeat upgraded.
Here is the liste of the packages upgraded without knowing which one could affect the functionnement of heartbeat :
libudev1 linux-generic linux-headers-generic linux-image-generic systemd-sysv udev

If you need more information I keep available.

Thank you for filing a bug on Ubuntu!

We believe this is a duplicate of https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1815101 , in the sense that the network configuration isn't restored to what it was.
