Satellite 5.2 - general slowness / unresponsiveness

Issue

• general slowness / unresponsiveness, especially for system registration and on web UI (such as configuration management pages)
• nearly every time navigating to different sections of the satellite server website, very long delay

• "top" command shows high resource usage by tomcat during this delay

• Satellite server takes time to react, some actions end up with error pages

• any web UI page having to do with config management loads especially slowly

• System registration times out or takes a long time

• Errors in /var/log/tomcat5/catalina.out logs, such as:
