Vulnerability in EPiServer.Forms
We're having a problem with our CMS5 R2-installations on our developer machines(these are all installations that have been migrated or are in the process of being migrated from 4.62).
After a requesting a page in the web browser, there is often a delay of 1-2 minutes before the page is loaded. After the page is loaded, EPiServer seems to generate excessive amounts of data traffic between IIS and the SQL-server.This traffic will persist until we perform an iisreset (the traffic is in the order of 1GB data received pr hour on the web server).
We've done a trace on the SQLserver to see what queries are being run, and it seems like it's a variety of stored procedures triggered by EPiServer that is causing the excessive data traffic.
We're kinda blank on what's causing this problem or how to solve it.Could this be related to:
We are runnning the same sites on w23k-server in the same domain and physical net as the database server(the same SQL-server that the developer machines are connecting against over VPN) and we experience none of these problems on these servers.
Hope someone have a clue on this one.. We're getting frustrated
I work with Fredrik on these sites that we're having problems with.I did a log on one of them now and though I can't make too much of it- EPiServer seems to be doing some extensive caching operations for a good 2 minutes before the start page is finally loaded.There are several hundred lines like this:

After two minutes, the front page is loaded in the browser- and these next log items starts filling up the log until I did an IISreset.

I've made the log in it's full glory available at http://www.iqas.no/upload/dokumenter/EPiServerErrorLog.txt (5.7mb)
It's worth noting that the initial caching is not just a one-time event, but it occurs every time you try and load the start page.
Did you find a solution on this problem. I have the same problem right now.
