I’m getting heaps of errors (about 1 per minute) in the Gatweay saying “MetricHistoryManager - Could not write metric value to database:database disk image is malformed” as shown below!

I’m not sure where to start to fix this.  
If you have any ideas please let me know.

Try this: stop the gateway, delete data/metricsdb/metrics.idb and start the gateway. That will create a new metrics database from scratch.
