Hi,
Friday, March 6th, around 16:30, the PG SQL instance stopped responding. Queries became extremely slow. When I tried to restart it from the UI, I received the message:
Operation failed because another operation was already in progress. Try your request after the current operation is complete.
However, I had not initiated any operation.
I then tried restarting it through the CLI. After a while it worked, although I’m not sure whether it was my action or if the instance recovered by itself.
After checking the logs, I found the following entry:
"status": {
"code": 9,
"message": "There is already a pending blocking operation for instance:(PII Removed by Staff), operation type: ROLLOUT, operation id: c9ec7013-4770-4d6c-b9a4-xxxxxxxxx"
}
However, I could not find any rollout operation listed in the operations history.
Additionally, in the CPU utilization metrics for the instance, there is a gap between 16:50 and 16:55.
Maintenance is scheduled for Saturdays.
Any ideas what happened?
