Thanks Ron. Yeah, I came across JBREM-409 a few days ago, and had already applied that patch from 1.4.6 (which seems to have been tagged in CVS but never released) to our code. So this problem definitely seems to still exist in 1.4.6. Upgrading the EJB implementation and going to Remoting 2.2.x is a bit more drastic, as we've been testing and tuning the current code base for months, and an upgrade of that magnitude could invalidate a lot of work.
