IIS 6 and 7 hangs with many web services

  • 772

I have an application that uses one web service asmx file per screen (like 50 screens), I didn't think this was a problem until we did tests.

I tried with IIS7 on windows 2008, it hanged. Since its new to me I changed it to IIS6 on windows 2003, the same thing happened

IIS 6 creates tons of w3mp.exe processes, each 55 MB, and reaches a point where the application is usless.

It has been used only by 10 people at the same time...

any thoughts?

iis web-services .net

    ok I found out what the problem was.

    First there is no diference between having multiple asmx files and 1 asmx file.

    second, the server hang because I'm using informix, and programmed the application with the informix client sdk 3.5, which hanged randomly opening connections. So I changed all the code to ODBC and it worked like a charm.

    third, we had 150 working processes on the connection pool, this created am w3mp.exe process per connection, it should have just 1 worker process.

    so, everything works ok now, hope this helps someone out there.
