We received a user report complaining that one of the published applications can not be opened. Login into the Citrix console, I noticed there are couple alerts regarding that single server which hosts the published application.
Health Monitoring and Recovery test failed.
Server lost connection to farm data store.
I checked the networks, everything looks fine. And the application can be executed while RDP into the server. So it must have something to do with Citrix. So I stopped the IMA service, and recreated the local host cache by running ‘dsmaint recreatelhc’, then started the IMA service. Tested it and found the issue was gone. I guess this might be cause by that the damaged LHC prevents the IMA service to update it from the datastore.
