I'm starting to see a few random errors in my logging that are coming through as:
"Unable to create Cookie because the page has been flushed" I have this happening on a few different sites/applications but we don't use the CFFLUSH tag or the CFHEADER tag in any of the apps that are randomly throwing this error. I did some more research on this error and the source is that the http headers have already been sent back to the client browser. Since we are not triggering this intentionally I found that there is a setting in the OpenBD admin that could be the culprit. The "Response Buffer Size" - which I believe is defaulted to "Buffer entire page" could be set to a specified number of KB, and as such once your output meets that number the buffer is cleared and sent to the client and subsequent data is written directly to the response buffers of the underlying server (tomcat in my case or jetty, etc). I checked this on my OpenBD admin and it is correctly set to the "Buffer entire page" setting... so I'm still not sure what is causing these random errors on our systems. My post here is two fold - One hopefully this information will help someone in the future and... Should I look at the tomcat default buffer size? I would think that logically that shouldn't be an issue because the OpenBD system should buffer the entire output prior to flushing the the tomcat response buffer --- which should mean that the size of the tomcat response buffer is not an issue at all. The second question is relating to how we configure our systems. We use the VivoTech installer for a single server install... does this mean that every application on the physical server share the same OpenBD response buffer? And if so, could multiple apps be filling up the response buffer such that it is triggering a flush? How would we test this theory (that is *IF* it holds water)? Is this related to how much java server ram we have set in the -Xms and -Xmx (or even the MaxPermSize / PermSize) environment parameters? Any thoughts, suggestions, help is greatly appreciated.
