Siteminder Web agent is installed on our web servers. At times, we start getting Error 500 from the whole website. SMAgentlog reports Error 500 as well as Error 20 2003. The only way to resolve is to restart the web server. Here is a sample of our SMAgent log.

Reported that 20-0003 errors occurred due to policy server restart. This error code, and error -1 calling isprotected, indicates that the agent can not communicate with the policy server. Upgrading to the newest web agent version will assure the latest bug fixes are in place in regards to connection management.
