Hi Julio, It looks like your clock is drifting fast and ntp is probably doing big adjustments. Running ntp more frequently would prevent such clock shifts.
For the second part, it looks like you are using a single controller configuration (not a distributed virtual database with group communication). I this configuration you cannot have transparent failover to another controller (which is basically what the message says).
