title: How do I resolve an IPC error in Open VMS web service integration toolkit (WSIT)
body: <p>I have inherited a 'technology' stack that I have very little experience of and am hoping for help to resolve an issue.  Using the OpenVMS Web Service Integration Toolkit to call OpenVMS service from a web browser I am receiving the following error:</p>
  
  <p>'com.hp.wsi.WsiConnectionException: ERROR: Transceive failure EndPointLocate: %WSI-F-FAILED_IPC_INIT, Unexpected failure while initializing IPC context'</p>
  
  <p>Switching on IPC debugging shows the following:</p>

  <p>I am guessing this is a resourcing issue but have no idea what needs to be changed.</p>
  
  <p>Any help very much appreciated.</p>
  
  <p>TIA</p>
