My problem ended up being Grizzly (version 1.9.21).
Switching to Jetty made the problem disappear, at least for the past 24 hours. Will keep you posted. I don't know if the issue is Grizzly itself or the Restlet connector, but this is a production system I can't play around with and test. Also, now that the Grizzly connector is being deprecated for Restlet 2.1, it seems wise for all of us to move away from Grizzly. -Tal On 11/15/2010 08:12 AM, Carles Barrobés wrote: > Ok, problem solved.
