I noticed this on my development install in the service-app.log, and then found it on my production install as well. It seems to only be logged upon start of the service:

Warning: connect.session() MemoryStore is not

memory, and will not scale past a single process.

My WebUI is on its own server, not on the BES, matches the OS of the BES and has 8GB of memory. We have under 10K endpoints and fewer than 10 concurrent users on the WebUI.
Is this something I should be concerned over?
