Maybe something to look at, in the pro version 8 i had the problem that seafile was starting with errors. But it was not clear what was causing this. After some troubleeshooting, i downgraded to CE version and the error was showing up when starting seafile.sh services.

Normally in the other pro version i also receive this error when exceed the limit. Right now in all the other logs it was not showing up. After fixing this by disable the user in the database, pro version was working right away.
