Tina,
Are you closing all the database connections, datareader objects,
memorystreams ?
you might want to try using the
using()
{
}
that i presume automatically calls dispose.
just to be on safe side call dispose.
Also you might want to look at application stress tool from ms
http://www.microsoft.com/downloads/details.aspx?FamilyID=E2C0585A-062A-439E-A67D-75A89AA36495&displaylang=en
Run it on your dev box. You normally dont stress test on dev. Try running
this tool to emulate user load on production box.
HTH
