Hi,

Since this afternoon, the replication slot folders have started to grow in
size again. I have attached a couple of screenshots showing the size and
some contents of a folder. Hope you find them useful.

I checked the database log at the publisher, and could find nothing
suspicious around that time when the spill files started appearing.

Thadeus Anand.
