Cause

This issue occurs specifically on VIP Enterprise Gateway version 9.11.2 when the Update Settings are set to Automatic. During the login, an unexpected file-reading exception during the unpaved LiveUpdate package processing, which corrupts the active console session state and prevents template execution.

Resolution

Access the page by removing doLogin.action from the URL and press enter to force a fresh session. (Example: http://localhost:8232/vipegconsole/doLogin.action)

To resolve the issue:

• Upgrade to VIP Enterprise Gateway 9.11.3 or later.
• If an upgrade is not possible, follow the instructions in this KB to apply the hotfix: HTTP 500 Error During Symantec VIP Enterprise Gateway LiveUpdate Upgrade
