This is on a subinstance, if that matters. Subinstance v2074 connecting to the main instance v2057. It also happened when I ran v2052 as a subinstance.

So in one case you had this problem when connecting version 2052 to version 2057?

We saw something similar to this, but it was just a one-off incident and it was not reproducible. It could also be an issue at the Windows operating system level as well.
