thanks very much!
the problem has been solved!
the details as follows:
Before I create this replication scheme, I have created a bidirectional replication scheme between the machine "admin1" and "timesten1". However, when I create this one, I only drop the replication scheme on "admin1" and this problem(TT12038）arised.
I don't know why, but when I drop the replication on "timesten1", the problem solved!
I think what you indicate is that you had 2 replication schemes in existence, and the problem was resolved when you deleted the old replication scheme?
Its probably not expected that there be multiple replication schemes between the same pair. I think if you intentionally want that in the future (sounds like you didn't want it here) that you should define a different replication port for each different replication scheme.
