I have plenty of processors for ajp13 running under tomcat, but tomcat and mod_jk seem
to lose communication and when that happens the tomcat process gets stuck running at
99% cpu utilization.
This occurs when I am just bouncing around the site for a while. When the page gets
stuck(does not load all the way) within that session and I refresh, I get another
stuck process. It's very strange. when I run the site through port 8080, it works
fine. No problems. Mod_jk2 does not cause problems, but does not load index file
automatically, which is why I am using mod_jk in the first place.
Any help is greatly appreciated.
Thanks in advance,
David
