Environment


Novell Access Manager 3 Linux Access Gateway
Novell Access Manager 3 Support Pack 3 applied
Auditing enabled for all Access Manager components

Situation

Access Manager setup successfully and users could access protected resources behind the Linux Access Gateway (LAG) without any problems. After about a week of operation, the LAG would appear to hang. No users could access the LAG, and no changes could be applied to the LAG. The LAG services were restarted (/etc/init.d/novell-vmc restart) and the LAG itself was rebooted, but the problem continued.

Looking at the /var/log/ics_dyn.log file, we could see the following information:

Resolution

Delete the cache of the audit platform agent on the LAG from /var/opt/novell/naudit/cache and make sure that the communication between the LAG and the Audit server is up.

The communication between the LAG and the NSure Audit server was down (Audit server had been taken offline) and all audit events were logged to the cache on the LAG, rather than being pushed to the server. The cache itself had grown to about 2GB of data without the Audit server coming back up again and the audit platform agent hung and refused to return the thread back to the application (the proxy). This audit platform issue has been reported to the Audit engineering team.

The ics_dyn.log file includes a message that warns administrators of the potential problem ("Novell Audit logging FAILED") as a troubleshooting tip.
