Help with DiagDebug report
am 09.11.2007 18:04:00 von SteveZohnI have been having intermittent hangs on iis6 in my envirorment. The server
runs a combination of asp.net applications and ISAPI extensions. The asp.net
applications are DotNetnuke, and there are about 20 sites running on this
server. We are running a modified version of DNN 3.2.2, and the most used
component is a custom iFrame module that makes web calls to both local and
remote servers. I mention this as I'm wondering if this is a result of
hanging because it is running out of connections.
Here is the summary from the report:
