BlobGCManager deletes just written extent.

I am attaching fragment of Azurite log. You can see that just written extent 6b079744-d236-4978-bba6-4d2b669f95c1 is deleted by the GC.

Run test that perform multiple GET/PUT/DELETE requests. After about 1 hour of testing GET for one of previously written objects permanently fails with HTTP error 500.

Have you found a mitigation/solution?

No

Thanks for reporting! Seems like a race condition. Newly created extent should had a protection period.
