CPU usage

[Ing. Cristian Galdini]

hi,
On my server i find that, after approximately one minute,
the processes MapAgent.exe and php-cgi.exe uses 100% of the resources of 
the CPU,
with whichever project (Sheboygan also, and also plans without some 
layer set up  ) and only opening Ajaxviewer, without to execute some 
operation , slowing down very many the system.
Someone has had experiences of this?

I use Windows S.O. , IIS and Php
