Hi there
We started enrolling users by external db and it worked ok. The external db is mssql.
Now we're using sync.php to synchronize enrolments with a db view, containing about 20000 roles.
Sometimes (not always) when I run sync.php, it unenroles all the users from one or two random courses and when I restart the script, everybody is immediately enrolled again...
Don't know what's going on here...
Are 20000 roles too much for sync.php?
