Troubleshooting:

  1. Check eventvwr of Citrix web interface for the farm where the application is installed.
  2. You might see errors like below:
  3. Log Name:      Application
    Source:        Citrix Web Interface
    Date:          3/15/2012 9:13:51 AM
    Event ID:      30107
    Task Category: None
    Level:         Error
    Keywords:      Classic
    User:          N/A
    Computer:      TESTSRV1.TESTLAN.LAN
    Description:
    Site path: C:inetpubwwwrootCitrixXenApp.

    The Citrix servers reported that they are too busy to provide access to the selected resource. This message was reported from the XML Service at address http://TESTSRV1:80 [com.citrix.xml.NFuseProtocol.RequestAddress].  [Unique Log ID: 999bcc67]

  4. Check the load on the reported server using “qfarm /load” command
  5. If you don’t see the server listed there then the Citrix XenApp on that server isn’t communicating it’s load to the farm DS.
  6. You need to have the reported server rebooted to get this resolved.
  7. In case, you have “Citrix Health Monitoring and Recovery” service running it’s possible that it can remove the app server from the load balance table that causes not to assign any sessions to this APP server again.
  8. Log Name:      Application
    Source:        CitrixHealthMon
    Date:          3/15/2012 9:27:31 AM
    Event ID:      2005
    Task Category: None
    Level:         Error
    Keywords:      Classic
    User:          N/A
    Computer:      TESTAPPSRV1.TESTLAN.LAN

    Description:
    Test threshold reached for the test XML Service test. The action to Remove server from load balance table will now be performed. The test is assumed to be in a failed state, and no more failure messages will be returned. An information message will be sent when the test is passed.
    Debug Information:
    Test failure 1. Error code: 25
    ** The previous test result was repeated 3 more time(s). **
    Test failure 5. Error code: 25

     

  9. In that case, disable the “Citrix Health Monitoring and Recovery” service and have the server rebooted again to let it participate in the Citrix load and get sessions created.

 

Fix:  Restart the IMA service if no go, Rebooted the reported server.
