Subject Re: Upgrade to 8.5.8/9

Hm, errno=111 is a connection refusal. Are you sure that your new
instance has an adequate number of threads available for httpd to
proxy to? Do you see any errors in your tomcat logging? If you do have
sufficient threads in the pool, then maybe there is something (like GC
pauses) hanging your requests that wasn't before and therefore
exhausting the pool causing rejections.
