hi everyone,
currently we are testing the performance our application (asp.net
based CMS) ... for that reason we wrote a "spider" that starts
webrequests for all relevant pages which results in filling the
pageoutputcache on server side.
so far so good. if we start one spider at once our application works
fine, but if we run more than one spider tool at the same time the
asp.net process works for a few minutes returning correct http output.
but suddenly (about 2-4 minutes after the spiders are started) stops
working correctly as only server errors are returned.
to bring the application back to a correct state we have to restart
the whole asp.net application.
the exception that is thrown is an IndexOutOfRange Exception. but it
doesnot seem to happen within our code, but before: during the page
compilation (see the stacktrace below from the eventlog-entry)
our script is called desktopdefault. aspx.
