Hi,

We have the 3 vCenters (5.5) which is connected with Linked mode, it's taking lot of time to login to the server or sometimes it fails with

Read time out

Unable to connect to vCenter Inventory service on "VCName"

I checked the  - vmware-sts-idmd logs and found many many errors like below

Any suggestion to resolve the issue?

As a workaround, we need to restart vcenter Inventory service (mostly all vcenter service)
