Hi shabbir,

Thanks for the valuable reply,

According to that article, we have to install debugger for find out the error that will happen in the next time. I can understand, but my question is whether my application may cause this error or not? if it is so then i have to check my asp pages for infinite loop,syntax errors..etc.But it is a very standard application and running for more than 4 years without problems.
Please kindly guide me.
