I just answered my own question.
CSCdy37701 Bug Details
Problem Description: In very rare situations when connecting via HTTP or
HTTPS (SSL) management session, LAN to LAN sessions and Remote Access Sessions
are not displayed under Administration | Administer Sessions and/or Monitoring
| Sessions. This appears to happen for sessions with SINGLE QUOTES (') in
the name.
Workaround: Telnet, SSH, or console connections sucessfully display the remote
access and LAN to LAN sessions. Remove the SINGLE QUOTE (') from the site
name.
