I finally found the cause of this issue. It wasn't the JRun internal webserver - it was a session cookie being set by our portal servers. The portal server cookie is set domain wide and even though it has a string prepended to "JSESSIONID" in its name it seems that occasionally JRun is getting confused by it. I've confirmed this by deleting the portal cookie; the CF cluster returns to normal operation immediately after this.
Thanks for everyone's suggestions. mxAjax / CFAjax docs and other useful articles: http://www.bifrost.com.au/blog/ 2009/2/10 James Holmes <james.hol...@gmail.com>: > We have an issue with our CF8.01 clusters in that sticky sessions will > intermittently break.
