I did not make a “red text” field as suggested. Instead I added a “warning triangle” that seats itself next to the question mark. When you hover over it it gives the requisite details of the Legacy/New Client status. This is true for both hosts and groups, and there’s a more direct amount of text laid out for the Service configuration page. (Cogs icon at top).
As for the segfaulting, I think it has something to do with the fact that fog spams the ftp_delete and ftp_rmdir REALLY MUCH. I mean the first error entry on the error.log has timestamp 21:17:21.586806 and the last 22:35:10.321097. In that timespan of less than 20 minutes, I have 996M of error.log just spamming the ftp_delete and ftp_rmdir warnings. There is 5351072 lines in my error.log on that timespan :)
