HTTP 500 Error During Symantec VIP Enterprise Gateway LiveUpdate Upgrade

Products

• VIP Service

Issue/Introduction

When attempting to upgrade Symantec VIP Enterprise Gateway from version 9.11.2 to 9.11.3 using LiveUpdate, the update process fails during the installation phase.

Symptoms:

• The LiveUpdate package downloads successfully, but initiating the Install step immediately redirects to the VIP Enterprise Gateway (EG) Console login screen.

• Attempting to log back into the console results in an HTTP 500 Internal Server Error.

• Refreshing the browser page at http://<Host>:8232 continues to trigger the 500 error, and the upgrade fails to complete.

Log Snippet (vipegconsole.log):

Environment

Product: Symantec VIP Enterprise Gateway

Affected Version: 9.11.2

Cause

This issue occurs specifically on VIP Enterprise Gateway version 9.11.2 due to an unexpected file-reading exception during the unpaved LiveUpdate package processing, which corrupts the active console session state and prevents template execution.

Resolution

Option 1: Apply Hotfix Patch (Recommended)

Apply hotfix patch 9.11.2_BRCMVIP-10230.zip to maintain automatic updates without console session crashes.

Note: This hotfix is strictly intended for VIP Enterprise Gateway version 9.11.2 only.

1. Download and extract the contents of 9.11.2_BRCMVIP-10230.zip.

2. Stop the Symantec VIP Enterprise Gateway service.

3. Navigate to <EG_INSTALL_PATH>/server/work/ and delete the temporary Jetty folder (for example: jetty-0.0.0.0-8232-vipconsole.war-_vipegconsole-any-).

4. Navigate to <EG_INSTALL_PATH>/server/webapps/ and back up the existing vipconsole.war file.

5. Copy the replacement vipconsole.war file from the extracted patch folder into <EG_INSTALL_PATH>/server/webapps/.

6. Start the Symantec VIP Enterprise Gateway service.

Option 2: Workaround (Manual Recovery & Update)

If you cannot immediately apply the hotfix, clear the stale LiveUpdate cache and switch to manual update mode.

1. Stop the Symantec VIP Enterprise Gateway service.

2. Delete updateInfo.txt from the configuration directory:

   • Windows: <VRSN_MAUTH_HOME>\conf\updateInfo.txt

   • Linux: <VRSN_MAUTH_HOME>/conf/updateInfo.txt

3. Clear the stale LiveUpdate package contents (delete all files inside the packages directory, but retain the directory itself):

   • Windows: <VRSN_MAUTH_HOME>\Liveupdate\packages\*

   • Linux: <SERVICE_USER_HOME>/LiveUpdate/packages/* (Default: /root/LiveUpdate/packages/* if executing as root)

4. Start the Symantec VIP Enterprise Gateway service.

5. Log in to the VIP EG Console and confirm the UI renders normally.

6. Switch to Manual Update Mode:

   • Go to System Settings > Update Settings > Edit.

   • Change Update Mode to Manual.

   • Click Save.

7. Navigate to System Settings > Update Settings > Check for updates to manually retry the upgrade.
