We got an email at 1418 saying the cluster had been automatically rebooted due to high memory usage.
We can now see 2 instances in the cluster (there was 1 before) and one of them (001) just keeps rebooting itself. The other (002) seems to be complaining in the logs about being unable to find a master node?
We've raised a support ticket but the SLA says up to 3 business days.
Anyone got any suggestions on what we can do in the meantime?
