Hi,
Have you tried to kill the application or its process? Or recycle the application pool?
This is very strange and it seems that something went into a loop.
Have you used SQL profiler to see which queries are being called?
Also, could you please use the
debugging options in Kentico to see what exactly is going on there?
Are there any errors logged in the Windows events or in Kentico
CMS in Site Manager -> Administration -> Event log?
Best regards,
Juraj Ondrus
