We have created a multi-server farm consist of 2 app servers dedicated for Search Service, in which all search components are running (except admin only in one server).
However we are getting error when do a search from search center or if you click on "Setup My Sites" from User Profile Application. I have checked the Event viewer, returns the error given below,
