Again, these warning messages and problems are occurring across multiple ( >8) floating desktop pools, comprised of both upgraded previously-working templates and brand-new templates built expressly for troubleshooting.
I find it highly unlikely that the desktops are the source of the issues considering that the only change on most of them has been upgrading the View Agent. It is worth noting the 6.0.1 agent works ok, and the 5.x agents work flawlessly on the same machines. All indications lean on the 6.1.1 agent (or possibly the connection servers) being the source of the issues.
I have had a ticket open for several weeks and VMware is currently just log hungry, I don't think there is any real answer on the way (e.g. I don't think the real answer to these problems is known yet).
