Ok, I've changed my setup but I'm still getting IDS|DDPLUS|HDS latencies
over 15 minutes right now.  Here's what my request looks like:
         
    51  request IDS|DDPLUS      ".*"    ns2.rutgers.edu
    52  request HDS             ".*"    165.230.4.74
    53  request MCIDAS          ".*"    yang.sprl.umich.edu
    54  request FSL2            ".*"    141.213.23.51

Futhermore, I see only one pqact running:
 
pluto.ldm> ps -aef | grep pqact
     ldm 23340 23337  0 19:54:02 ?       12:28 pqact

What do I need to correct?  

Thanks,

Chris
