What kind of inconsistencies?

Barring a mysql bug (hopefully unlikely), and given that WMF slaves are -supposedly- unaffected I can only think in a configuration difference which is affecting in the interpretation of the replicated statements. Is toolserver ignoring some tables? I remember a mysql bug where actions on ignored tables corrupted replication (but I thought it was fixed!). _______________________________________________ Toolserver-l mailing list (Toolserver-l@lists.wikimedia.org) https://lists.wikimedia.org/mailman/listinfo/toolserver-l Posting guidelines for this list: https://wiki.toolserver.org/view/Mailing_list_etiquette
