problem with reserved project

[alexey.sher]

Hello, everyone.
I work as an engineer in a company. We have a project implemented in WinCC OA. The project is redundant, implemented on two servers and several client machines (Remote UI). Noticed this feature - when you turn off one of the servers (power off) on the client machine begins to slow down the project at intervals of exactly 60 seconds. It is impossible to work for 20 seconds every minute - the mouse cursor does not react to anything. And so it continues until you enable the previously disabled server. Most likely the project on the client machine (Remote UI) tries to connect to the second server. Perhaps this is correct, but why is it so critical to the health (the second server at the time is available and functioning)? I may have set up the project incorrectly.
Help to understand.

-WinccOA 3.14
-2 Server Based on Linux OpenSUSE with 2 different ethernet cards
-2 Client Machine on Windows 7 64bit with 2 different ethernet cards
-Redundant Network Connections (2 LAN 172.29.22.XXX and 172.29.23.XXX)

Thank you in advance.

Please check the settings in the hosts file of the operating system on the client machine.
In the hosts file you have to define the IP addresses and hostnames for the WinCC OA servers to ensure that the name resolution is working.

Verified. Checked the command "ping Server 11", "ping Server 12", "ping Server 21", "ping Server 22" - everything works.
Here is the config file on the client machine
[general]
pvss_path = "C:/Siemens/Automation/WinCC_OA/3.14"
proj_path = "C:/WinCC_OA_Proj/RemoteUI_2"
proj_path = "//172.29.23.200/WinCC_OA_Proj/BAES4"
proj_path = "//172.29.23.201/Test/BAES4"
proj_version = "3.14"
langs = "ru_RU.utf8"

data = "Server12,Server11$Server22,Server21"
event = "Server12,Server11$Server22,Server21"

mxProxy = "none"

[ui]
defaultPanelFormat = "XML"
LoadCtrlLibs = "AnalogInput/AI.ctl,navigation.ctl"

The hosts file from the client machine
172.29.22.200 Server11
172.29.23.200 Server12
172.29.22.201 Server21
172.29.23.201 Server22

According to the help file this configuration is not 100% correct. Not sure if this is your problem, though.
(See help "Special functions\\Redundant network connections")

The help especially states that the aliases used for the redundant connection must have "-1" and "-2" added to the name.

The entries with -1 and -2 are aliases for the redundant network connections. The aliases must not be the same as the host name. You can also use other alias names for the connections than the -1 or -2.
! Note however, that the options -1 and -2 must be added to the alias name used.

EXAMPLE:
Hosts file entries:
192.168.153.135 VRA-TST-W-323 reduServer-1
192.168.120.156 VRA-TST-W-323-2 reduServer-2
192.168.153.108 VRA-TST-W-322 reduServer2-1
192.168.120.131 VRA-TST-W-322-2 reduServer2-2

Config file of the redu project looks as follows:

data = "reduServer-1,reduServer-2$ reduServer2-1,reduServer2-2"
event = "reduServer-1,reduServer-2$ reduServer2-1,reduServer2-2"
