W3wp.exe

Hi,

I just want know what is exactly this process, beacause I have lot of them running in my server, and they are filling my memory. The server is used for an ASP intranet. The server is a Windows Server 2003 with IIS 6.0.

Thanks a lot.

Hi

it is worker process in IIS 6.0 (essentially all user code runs in such). There is one per application pool by default (unless you use web gardens)

Hi

w3wp.exe is a process associated with application pool in ISS.

If you have more than one application pool, you will have more than one instance of w3wp.exe running and usually allocates large amounts of resources.

see here for more infohttp://www.liutilities.com/products/wintaskspro/processlibrary/w3wp/

and herehttp://support.microsoft.com/kb/900243 in case you want to find why the W3wp.exe process consumes up to 99 percent of the CPU resources every several minutes on a Windows Server 2003-based computer.
