<p><span style="font-family:"Calibri",sans-serif;color:black"><o:p> </o:p></span></p>
<p><span style="font-family:"Calibri",sans-serif;color:black">For a couple years ago we had similar problems with to high volumen of messages/communicaton between harvesters and HarvestJobManager and the GUIApplication. The GUI hang and messageques where overloaded
with too mutch trafic. We lowered the number of calls, minimized retries, and delayed answers and repsonses in the settings files and perhaps also in the code. The last thing did Colin - i don't remeber where in the code.<o:p></o:p></span></p>
<p><span style="font-family:"Calibri",sans-serif;color:black"><o:p> </o:p></span></p>
<p><span style="font-family:"Calibri",sans-serif;color:black">I have attached relevant common snips from our GUIApplication, HarvestJobManager and and broadcrawl Harvester settings files.<o:p></o:p></span></p>
<p><span style="font-family:"Calibri",sans-serif;color:black"><o:p> </o:p></span></p>
<p><span style="font-family:"Calibri",sans-serif;color:black">If the trick is hided in the NAS code section for default values i need to investigate that further together with Colin.<o:p></o:p></span></p>
<p><span style="font-family:"Calibri",sans-serif;color:black"><o:p> </o:p></span></p>
<p><span style="font-family:"Calibri",sans-serif;color:black">Which options do you use for your imqcmd listning?<o:p></o:p></span></p>
<p><span style="font-family:"Calibri",sans-serif;color:black">Normally I only use the imqcmd list dst to see if there are something wrong with the JMS queues. <o:p></o:p></span></p>
