AWS Redshift cluster instance restarts outside of maintenance window

0

Hi, We have noticed our AWS Redshift cluster instance restarting outside the maintenance window. Last Monday , Sept 11 we have a restart outside our weekly maintenance window. This has occurred in the last 6 months on a regular instance. Is there any way I can establish via logs what caused the restart of the instance as per event notifications.

I've read the post re: generic causes, but I want to find out the specific root cause. Thanks.

e.g. 3 days ago Sep 11, 2023 11:52 AM Cluster 'j2bi-redshift-pub' completed restart at 2023-09-11 10:52 UTC. j2bi-redshift-pub Cluster REDSHIFT-EVENT-3520 Monitoring 3 days ago Sep 11, 2023 11:51 AM Cluster 'j2bi-redshift-pub' began restart at 2023-09-11 10:51 UTC. We will attempt to park database connections for the duration of the restart. j2bi-redshift-pub Cluster REDSHIFT-EVENT-3519 Monitoring

Hi,

Please open a support ticket as that should not happen. Support will provide reasons for that restart.

Bests!
