Solution
Version:  Network Sentry Appliances running 3.x or 4.x firmware (Firmware is listed in the Dashboard Summary panel)

Issue:   Very slow access to tomcat-portal or in some instances tomcat-portal will not respond at all. This leads to delays or the inability to access remediation or isolation pages.

The following messages are found in apache error_log:
