Question:

What could be one of the many causes of the "TCP Message timed out"  message

Answer:

It could be an LDAP delay causing the requests to pile up and retry, putting the ldap performance into a degraded state on the  server, unless it can cleanup faster. 

Additional Information:

The RequestTimeout parameters are set in the Host Configuration file, SmHost.conf.

Settings in the Host Configuration File apply only when the trusted host initializes. Once the trusted host initializes, the settings in the Host Configuration Object take effect. Request Timeout Use the RequestTimeout parameter to specify the number of seconds that the trusted host should wait before deciding that a Policy Server is unavailable. This setting allows you to optimize the response time of the Web server. The default value is 60 seconds. Note: If the Policy Server is busy due to heavy traffic or a slow network connection, you may want to increase the RequestTimeout value.
