IMS Error: All interaction engine nodes in node set are unavailable RRS feed

  • Question

  • Hi,

    we have 3 collections, with around 2 million articles, that we search through one published search profile. We have 2 IMS nodes, and we've increased available RAM for each of them to 4GB. When we try to search this profile from our web application for more then a couple of times in a minute, we get the following exception:

    ERROR: Ims.Search.SearchExecutor(): Error: All interaction engine nodes in node set  are unavailable

    Microsoft.Ceres.InteractionUI.Wdm.NoNodesAvailableException: All interaction engine nodes in node set  are unavailable

       at Microsoft.Ceres.InteractionUI.Wdm.SearchHandler.ProcessSearchRequest(Context context)

       at Microsoft.Ceres.InteractionUI.Wdm.SearchHandler.ProcessRequest(HttpContext context)

    This happens even when only one user is using the web application. Do you know what could be causing this error and how can we prevent it from happening?

    Thanks in advance and kind regards!
