Thanks for the response Sean,
We are not running any load balancers. We have two configurations but the error occurs on both: Web Server A (IIS 6, asp pages) < > Web Server B (IIS 6, ServletExec, Midtier) < > Firewall <> Database Server Web Server A (IIS 6, asp pages, ServletExec, Midtier) < > Firewall < > Database Server This occurs even in the second example where everything resides on the same web server. I don't believe the firewall is a problem since both of these configurations work fine for the majority of people. They will be using only one of the above during their session (no crossover). The Remedy forms are running inside of iframes within asp wrapper pages so people access the web site pages via IIS and those asp pages call the Remedy content either via direct ViewFormServlet calls or jsp redirect files within the iframes. It may be a problem between IIS and ServletExec though and it gives me something else to look at. I may also have to consider testing with a different Servlet. I'm not sure I understand what you mean by connecting directly to ServletExec since it resides within IIS on the default site? I'm no IIS expert so any recommendations on what settings to look at/tweak would be helpful.

Are you running anything like this: Web Server A Servlet Exec A Firewall -->Load Balancer------> Firewall ------>Load Balander----> Web Server B Servlet Exec B If you do "Web Server A" could have a session to "Servlet Exec A" and then magically switch to B in the middle of a transaction and cause this error to occur. If I understand right this error has to do with the connectivity between the "Web Server" and the "JSP Engine" whatever that might be (in your case it is Servlet Exec). There may be a timeout setting on your web server that is causing this issue to occur. If you connect directly to "Servlet Exec" then you probably won't get this error. I am assuming you are running Apache or IIS for you web server ... so it may be a timeout setting on the connection between the web server and servlet exec. Hope that helps ...

By intermittent, the application works great for everyone most of the time but occasionally, the following error pops up: "Unable to set up a data connection, which is preventing the application from working correctly. (ARERR 9351)" We're behind some firewalls and this pops up in a browser session while performing a save and/or performing a retrieval of information. Our midtier is located a couple thousand miles away from our database server and the midtier and database are set to use a specific port. Our assumption is that at that moment, there is a brief connectivity problem that causes this-especially since it appears more often at certain offsite locations that at others. We have submitted a ticket to BMC since the error guide simply adds "An internal error occurred during a back channel request from the browser to the mid tier server." I'm basically looking for anyone who might have more information on what underlying problem would cause this specific message? What kind of back channel request? It is related to something specific that we could possible code around? Any ideas are appreciated. I'll be turning on all of the logs and looking for an answer but wanted to tap the combined expertise for possible remedies...
