Thanks Igor for the reply. Sorry for not knowing quite enough to be specific with some of this. When I say it hangs, I mean every once in a while it takes 15-20 seconds to respond. When I have a direct Tomcat connection setup it doesn't happen.
mod_status was a great suggestion I did not realize was there. I'm not sure how I can use it though to debug this type of problem when many of the requests go though fine and one does not once in a while. I removed everything that was default per your suggestion. This is my new configuration: <VirtualHost 192.168.XXX.XXX:80> RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} </VirtualHost> <VirtualHost 192.168.XXX.XXX:443> ServerName 192.168.XXX.XXX ProxyPreserveHost On SSLEngine On SSLCertificateFile /etc/httpd/ssl/jirassl-pem.crt SSLCertificateKeyFile /etc/httpd/ssl/jirassl.key ProxyPass / http://localhost:8080/ disablereuse=off ProxyPassReverse / http://localhost:8080/ </VirtualHost> I also added the diablereuse key. I have not used the AJP connection since the warning message about an open proxy scared me off. Would this be an issue for a reverse proxy? Would this cause issues that last a long as I am seeing? I have a capture of the problem in a wireshark log. Is there something I can look for in there that would point me in the right direction to filtering his down?
