Hi Matteo, thank you so much for your reply!
We're using the default javascript method.
Our server is hosted @ http://ads.brasilct.com
And we're running banners on multiple sites:
- On http://www.santanderesfera.com.br (there's a box with 8 positions under the title "Ofertas do Programa SuperBĂ´nus")
- On https://esfera.brasilct.com (most of the images on that page)
- On http://vitrine.santanderesfera.com.br
Our current server is delivering about 25MM impressions/month regularly. This issue appears to be happening only with Chrome browsers, either on Windows and OS X.
If you go to any of those pages using Chrome and navigate/refresh them a few times, suddenly your Chrome won't be able to load any images (see this screenshot: https://www.dropbox.com/s/j69qiipdc76f9ys/revive%20error%202.png?dl=0).
If you clean the cookies from ads.brasilct.com or start a incognito window, it'll work just fine.
One interesting thing to notice: when you try to access Revive's admin page, you get this message from Apache:
Bad Request
Your browser sent a request that this server could not understand.
Size of a request header field exceeds server limit.

(see this screenshot: https://www.dropbox.com/s/2r96a2f50enjhn4/revive%20error%201.png?dl=0)
At first, I thought it was related to administrators and managers (or anyone who might be logging on Revive's admin), but it happens to any Chrome user who happens to access our sites repeatedly.
Our setup and needs are very simple. I've already tweaked the server settings, disabling all advanced features that we don't use for targeting or specific delivery, but with no luck so far.
Please let me know if you need any further information on server settings or any other thing related to our setup.
Cheers and thanks a lot in advance,
Eduardo
