[Enterprise 2.0.0p3] Incorrect service state in dashboard, but correct in FullScan

After some time of using version 2.0.0p3 we faced strange issue with the services state.

Checking service in dashboard shows "Unknown" state:

If I'll perform Full Scan - zero vanished services will be found and the same service will be in the "OK" state:

I tried to move this service to “Undecided” → Apply Changes → add service back → Apply Changes = same result.
Also tried to use: Actions → Remove all and find new.

Interesting that If I'll create copy of this host and scan it for services, the same service will be shown as "OK":

Configuration on the device exist and service should be in the OK state:

ru-spb-csw-01#sh run int vlan 1339
Building configuration…

Current configuration : 279 bytes
interface Vlan1339
description intVL1339
ip address
ip helper-address
ip helper-address
no ip redirects
no ip unreachables
ip verify unicast source reachable-via rx

I checked all rules that apply to this host/interface, not found any that can affect interface state.

Part of **cmk -D** for this host

OMD[o2x_cmk]:~$ cmk -D ru-spb-csw-01

Anyone that faced similar issue here? Would be glad to hear any suggestions :slight_smile:
