Hi
Just some suggestions:
Are you logging triggers? Might be worth clearing out old log files, see item 4
here. If you manually delete logs MFP should be shut down before.
Also if you are confident your triggers are working well it may also be helpful to switch off trigger logging.
I think it is a good idea to shut down MFP periodically and manually do Windows updates etc. I do mine once a week.
I don't think there were any API issues last night, I was running live and see no errors. However, another possibility could be loss of internet your end.
