Question

Hi, When I try to create a new project from the WebHome in the Tracking web, I see that my server tends to get froze for some time. "Create New Project" does not create any page and after quite some time I get an "HTTP 500" error.

I logged on the the webserver and saw that when I try to create the project, the system tends to sit in some sort of loop...trying to Read the page that it is trying to create. A similar problem was observed when I tried to install the "ProjectPlannerPlugin".


Attached is the debug output obtained by doing a strace on the "view" process that is trying to serve the page
