Just following up in case future travelers see this…this was, indeed due to thread contention. Using GbsSession>>critical: (as documented) in this errant thread and the main thread worked around the bug (I have GS objects leaking into one of my services).

I’m now dead in the water with the following error occurring on the VW client within a couple minutes of startup each time. I’m at a loss as to where to look for root causes for this…I’m guessing I’m doing something that I shouldn’t. My first guess was threading…but I’ve gone to great lengths to avoid any DB objects ending up in the other threads. If that seems like a likely culprit, I’ll dig deeper. Any hints? :)
