Relation between writing projection checkpoints and dropping CatchUpSubscriptions based on them

I am using ES 4.1.1 hotfix on Win server 2016.

Subscriptions are run in docker containers as .net core apps.

It seems (by looking into logs) that CatchUp subscriptions drop with ConnectionClosedException when checkpoint for related projection is written by ES.

Is this expected or is it unrelated and is just a coincidence?

Best regards


I can’t see how it would be related. My guess unless further information came about is that it is coincidence.
