Spoke too soon. My FF is having the same intermittent issues as IE11 but it works a lot better than IE11.
Weird. I can wait exactly 15 minutes, and the site works ok for about 3-4 refreshes / page changes, etc.... then the same thing happens. The browser page "hour-glasses" for a while and displays the browser error message.
I tried clearing the cache on my FF browser but it didn't fix the issue.
I have verified multiple times the following points for my particular situation with 2 separate Win 7 PC's and both IE11 and FF:
- The problem is specific to this site. All other sites are working ok.
- The 15-min "wait" phenomenon is consistent with IE in particular.
FF, it's working a lot better but randomly intermittent. For example, I just did ~20 page refreshes in FF and it's working ok.
With IE11, I can't do more than ~3 refreshes, then the browser error appears and I have to wait 15 min's before trying again.
