 When I run systemctl list-units carbonio* I get:

Is the failure of "Carbonio Services" causing this random issue? Should I try and reset my Carbonio Mesh Credentials? One other thing that might be relevant is that I notice that the newer versions of Carbonio are particularly memory hungry. I run a small installation with less than 10 users and this software is using almost all of the 16 GB plus some of the virtual memory: 15.6 GiB total / 460.7 MiB free / 235.46 MiB cached. Any advice would be welcome as this is starting to become a major problem for me.
