Hope that gives you something to check anyway!

The Roman Empire fell due to a large, corrupt government, overspending, an overextended military, insecure borders, and the illegal immigration of Goths, barbarians (anyone who was not educated), and religious fanatics. Sound familiar?
"..it does not require a majority to prevail, but rather an irate, tireless minority keen to set brush fires in people's minds.."
--Samuel Adams

I click on IC, then I click on "View New Content", and a list of threads comes up. I read a thread, click the "back" button on my Windows browser, and sometimes it goes back to the list of threads, and sometimes it comes up blank and says "No new content". No rhyme nor reason to it - sometimes I can read 6 or 8 threads before it "blanks", other times I only read one, then click back and the new content is gone. Very frustrating.....
The only filter I have selected is "content I have not read".

This may be something to do with cookie expiration, but I dont have an explanation as to how the "back" button triggers the condition.
I'll start with the typical question
1. Browser type and version? (example: Internet Explorer 9, or Firefox 13)
Also, when it happens - take note of the time and how many users are on when the incident occurs. I'm curious if the issue happens under load.

On another note - This is the only forum where this issue presents itself. Several others that run this (or very similar) software function fine on my machine.

The cookies are used to identify the relative "new content" based on what you've looked at. Granted, based on what you've said, you should only see the problem once a week. If you have some other, more aggressive, cookie policy, that might be the culprit. I think that Abolt is using the same setup ie9/w7.
I guess I'll be showing up for a week or 2 using ie9 on win7. I'll let you know if I reproduce the issue.
Thanks for confirming about the load too..

This site is load-balanced across multiple servers? That surprises me. It must get a lot more traffic than I thought. One decent-sized web front end can handle quite a lot of "view" traffic and even a good amount of concurrent transactional (e.g. posting) operations. I assume it's on VMs. What are the WFE specs?
Or is it just LB for high availability, not for performance?

No problem. Thanks for trying to help me figure it out.

Yes, it is LB/HA (active server/fault tolerance).
The site serves as a reliable source for many. So, whenever we would have a significant vote or ruling, the site would nearly crash due to the load. In fact, Chris and I had to do a fair amount of scrambling in May 2011 just to keep things responding within 15/30 seconds. Since the load balancer configuration was implemented, we have been able to handle the heaviest traffic without any issue whatsoever. The forum software upgrade has also helped to some extent. ..but yea, you'd get 300 anxious folks, concurrently hammering the "view new content" button, and things would start shutting down on the old server.
We are are actually running on physical HW. These services are provided to us by our top notch provider, TechPro http://techpro.com

Do you consistently log into a single machine?
Or do you log in from home at night, at work in the morning, and then via a wireless at lunch? I think your issue may be the result of switching various machines. If this is the case, are you using win7/IE9 on all of them?
