Hi @kcheng,
Thanks for sharing the details. This looks like behaviour that will need workspace‑specific investigation by Databricks Support, rather than something the community can reliably diagnose or fix.
Because it resulted in a sudden, large volume of auto‑created alerts, I’d strongly recommend raising a Support ticket with your workspace URL, region, and a rough time window when the alerts appeared. That will let the Support and engineering teams check backend logs, confirm whether this is expected behaviour, and advise on safe cleanup options.
If this answer resolves your question, could you mark it as “Accept as Solution”? That helps other users quickly find the correct fix.
Regards,
