Fehler in der Replikation von PostgreSQL

[minimike]

Hi

Ich habe die Tage zum ersten Mal einen Replication-Cluster aufgesetzt. Zwei mal RHEL 6.4 mit PostgreSQL 9.1- Der Master ist Echtblech und der Slave ist eine VM. Ich bekomme jetzt aber auf dem Slave folgende Meldungen in den Logs

Frage kann ich jetzt davon ausgehen das die Daten auf dem Slave nun Müll sind? Und wie könnte ich das optimieren? So das es nicht mehr auftritt
