EAP Shutdowns while using admin-console due to broken "X connection to localhost"

Issue

• When interacting with the Admin Console on a desktop browser, the instance of EAP booted on a remote linux machine dies.
• The Admin Console works fine for some time and then suddenly encounters this problem.

• On first access to the Admin Console, the EAP console output shows:

  15:04:43,670 INFO  [ServletContextListener] Welcome to Seam 2.1.0.SP1

(Note that the WARN messages themselves are not symptomatic, just the location of the failure relative to the log messages.)

• Server log shows same minus the "X connection to localhost..." line
