Setting socket timeout on ActionScriptAdapter?

I have an application that is using BlazeDS for two-way communication between a Java-based server hosted on Tomcat and a Flex Client.  From one particular client access location (and no others we've seen), the server is throwing a java.net.SocketTimeoutException as shown in the Stack trace below.

I believe I could solve the problem by increasing the socket timeout setting, but I can't find where to do this.  I am using a subclass of ActionScriptAdapter which, unlike the HTTPProxyAdapter, does not appear to accept an HTTPConnectionManagerSettings object to specify the timeout.

I am thinking I may be able to set this value via the initialize( id , ConfigMap ) method, but have found no documentation on the allowable properties that can go in the ConfigMap argument.

Any help greatly appreciated.  Partial stack trace for the error is below:
