so, can you try your load test with a map without the imagery? I ran into
this exact problem in the past, only with MapGuide Enterprise 2008 and the
Autodesk Raster image provider, so I'm wondering if you might have something
similar going on with the open source raster provider.</FONT></SPAN></DIV>

<P class=MsoNormal><SPAN lang=EN-US>We have experienced a problem with the MGOS
2.0 installation. After some time with moderate load it just returns grey images
until the “Mapguide Server v2.0” service is restarted. We are using the WebApi
with the GETMAPIMAGE mapagent operation. <o:p></o:p></SPAN></P>
