Improvements to Session Server's Handling of Heavy Load (31430, 29967)

Symptom:

When the session server was under heavy load, it generated errors when it added or removed new sessions from the session server database tables. At the same time, the session server also stopped removing expired and idled-out sessions from the session store. These issues were caused by maintenance queries taking longer than what the Policy Server allowed in the default query timeout setting.

Solution:

In this service pack, all of the issues listed above are now fixed. The Policy Server can now better handle longer-running session server maintenance task queries-such as removing idled-out or expired sessions-using a new MaintenanceQueryTimeout registry setting.

You can modify the MaintenanceQueryTimeout setting at the following location:

HKEY_LOCAL_MACHINE\SOFTWARE\Netegrity\SiteMinder\CurrentVersion\SessionServer

The default value is 60 seconds. However, if the session server is under heavy load, you need to increase this setting to a value large enough to allow the maintenance thread to complete all tasks successfully.
