SAS Viya on Azure randomly throwing 503 after start/stop

paul-blu — Tue, 06 Jan 2026 16:52:52 GMT

Yesterday, our SAS Viya cluster on Azure randomly started having 500 Internal Server Errors, so we decided to restart the instance to try to fix it. Now, the "Start" command succeeds, but we just get 503 from the SAS Viya URL. Unfortunately, I don't even know where to start to debug what the issue is because I just get permission denied errors everywhere in Azure. Below is a screenshot of our AKS monitoring results, which is pretty much the only thing we have access to view.

Our entire production system is down because of this, help would be greatly appreciated!

Are you using Azure Marketplace or just "normal" Azure? With normal Azure and the standard SAS licensing agreeement opening a SAS Tech Support track is your best option.

We are using Azure Marketplace Pay-as-you-Go. We don't have the standard SAS licensing agreement.

Note for all - @paul-blu shared the Azure subscription and Managed Application details for his Pay-as-you-Go Viya instance privately with me and we were able to get the system back up and running for him. The issue was that the Viya Postgres database had run out of space.
