--------------------------------------
Hi,
On main Jenkins machine:
{noformat}
root@serv1 ~ # cat /etc/hosts
### Hetzner Online GmbH installimage
# nameserver config
# IPv4
127.0.0.1 localhost.localdomain localhost
88.99.242.108 serv1
#
# IPv6
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
2a01:4f8:10b:2ab::2 ip6-serv1 ip6serv1
{noformat}
(that's the default of Ubuntu). Keep in mind that Ubuntu uses ip6-localhost for
ip6. All Jenkins machines use IPv6 as full featured internet connection, IPv4
is only "backup".
Here is solaris:
{noformat}
jenkins@serv1-vm3:~$ cat /etc/hosts

{noformat}
(standard on solaris).

> Upgrade ZK dependency to 3.4.13. This fixes ZOOKEEPER-2184 which will make
> the ZK client re-resolve the server hostnames when a connection fails. This
> will fix issues where a failed ZK container is replaced with a new one that
> has a different IP address and DNS gets updated with the new address.
> Typically these upgrades do not require code changes, but that should be
> verified.
