Fails to login to Aria Operations for Logs Web Interface

Products

• VMware vRealize Log Insight 8.x

Issue/Introduction

• Users with a valid username and password may fail to log in to the Aria Operations for Logs Web Interface. After the username and password are entered on the Web Interface login screen, the Web Interface is not displayed.
• A similar error is displayed in the /storage/var/loginsight/apache-tomcat/logs/catalina.log file:
  [https-openssl-apr-###-exec-1] ERROR org.apache.catalina.session.PersistentManagerBase Swapped session [<Session_ID>] is invalid

Environment

Aria Operations for Logs 8.16.x
Aria Operations for Logs 8.18.x

Cause

The issue is caused by incorrect reference counter handling in a specific version of the Java Runtime Environment (JRE) used by the LogInsightDaemon process.

Resolution

VMware by Broadcom Engineering is aware of this issue and is working to resolve it in a future release. In the meantime, please use the workaround provided below.

Workaround: 

1. Log in to the appliance via SSH using the root account.

2. Find the PID of the Tomcat process:

   ps aux | grep tomcat 

3. Kill the Tomcat process:

    kill <PID of Tomcat> 

4. Wait a few minutes until the Tomcat process automatically restarts, then try to log in again to the Web Interface.

Note: Tomcat is a related process that works with the LogInsightDaemon. Restarting Tomcat also triggers a restart of the LogInsightDaemon.
