RDS instance stuck in rebooting

Hi Michael,

Please refer to this troubleshooting guide [1] to try and resolve the issue. Although this is for MySQL, this will help you debug the problem.
In case, the instance is stuck in rebooting for a longer period of time (a few days), contact AWS Support, as this could be a system-related issue.

I can see that the reboot completed. It looks as though your database had a very large amount of crash recovery to perform in order to complete the reboot. Also, your workload is consistently consuming 100% of the available throughput to EBS on the instance type you are using.
