stacktraces when closing opi screen with CA PVManager connection

[berryma4]

I get one of these for every pv on some of our status pages (the stacktraces really spin).
But, not all screens do this. I'm not sure where the issue is yet.

I'm guessing it is a specific widget type, or how it is used, considering I only see this on our status screens.
