db.reseterror() in mongo not rid of this. inserts confirmed collection. code here: https://github.com/nanothermite/playrctmongo

any suggestions?

override in logback with:

<logger name="reactivemongo.api.failover2">     <level value="info"/> </logger>  <logger name="reactivemongo.core.actors">     <level value="info"/> </logger> 

this silence only abusive debug messages of reactivemongo
