Create a parallel testing environment (in fact, any place that locked
down should already have one), and try tweaking the firewall settings in
that environment;  another possibility is to have the appserver serve
only from its cache for a "long" time (e.g., while repeatedly serving
the same page), and then request a page (e.g., search, or something)
which needs objects not already in cache.

Once you can provoke the problem at will in the test environment, *then*
you can begin tweaking the firewall to keep it from closing the socket
between the appserver and the storage server (if that is your problem).
Once you can prevent that in test, *then* you can push to have that
change rolled to production.
