Since you have 30 consumers, I believe each one needs a different syncrepl rid and the error string of "value #0 provided more than once" might be related to that, so maybe you need to change them on each consumer?
This information is incorrect. RIDs are unique inside a consumer. Different consumers can use the same rid with no issue.
