Requests to Access Manager server via a Distributed Authentication UI triggers exceptions in the distAuth/amProfile_Client log and the Access Manager server debug/amProfile_Server log. After numerous sessions, the amProfile_Client log can grow to several gigabytes, and the Access Manager server amProfile_Server log can grow to several megabytes. No loss of functionality is caused by these exceptions in the logs, but they can cause a false alarm for users, and potentially the logs can fill up the hard disk space.
Workaround. Run cron jobs that will make the contents of the log files null. For example:
On the Distributed Authentication UI client machine, run "cat /dev/null > distAuth/amProfile_Client" every few hours, depending on the traffic volume.
On the Access Manager server, run "cat /dev/null > /var/opt/SUNWam/debug/amProfile_Server" every few days, instead of every few hours.
