Received Session Timed Out Error in the Admin UI When Trying to Manage a Policy (48806)

When working with huge policy store, the Admin UI applet throws the "Your session may have timed out" error. This was due to the Admin UI applet trying to send a request to the policy-server using the TLI layer, which generates an exception. The problem was caused when the data received from Admin clients exceeded the dynamically allocated receive TLI buffer at the policy-server. The data is not received successfully at the policy-server and the connection was terminated, and Admin UI displayed the error. The value of maximum allowed size of TLI buffer at policy-server for handling Admin UI messages was set to 32KB.

This is no longer an issue. The buffer size for Admin UI and Policy Server communication is configurable using a registry key:

HKLM/Software/Netegrity/Siteminder/CurrentVersion/PolicyServer/Max AdmComm Buffer Size

If this key does not exist or has a value less than 256KB, the minimum default value is considered as 256 KB.
