Sun Java System Access Manager 7.1 Performance Tuning and Troubleshooting Guide

Access Manager server hangs when multiple clients point to one Access Manager server instance

When multiple clients point to an Access Manager server instance, the session polling mechanism used prior to Access Manager 7.1, can cause the Access Manager server to hang. The older polling mechanism was based on caching time.

Solution: Upgrade to Access Manager 7.1. In the 7.1 version, the session polling mode is configurable. You can use on either caching or idle time mode. By default it is based on the idle time.
