Restic backup hang toward the end of the b2 backup. No ETA displayed.

Output of restic version

restic 0.12.1 compiled with go1.16.6 on linux/amd64

How did you run restic exactly?

restic --repo=b2:my-bucket backup --ignore-inode /data

What backend/server/service did you use to store the repository?

Backblaze.

Expected behavior

Expected restic to complete, or go to the next file. Also for a strange reason, restic was not displaying ETA for the completion which I normally see.

Actual behavior

Restic stayed on the file for at least 5 days, after which I terminated the process with SIGABRT. Log attached.

Steps to reproduce the behavior

Not been able to repro. This was the first time backing up this repo.

Do you have any idea what may have caused this?

No idea. No parent snapshot was available, as this was my first run. Now running again, and checking if it completes.

Do you have an idea how to solve the issue?

No idea, but hope the logs help diagnose the issue.

Log file, last 1820 lines of the log, including the stacktrace after the SIGABRT I hope: stuck_restic2.txt

Terminal output for the last five days. The time kept increasing, but no progress seen:

Did restic help you today? Did it make you happy in any way?

Restic is awesome. See forums for my numerous postings, including success stories. I backup over 130TB of data with it efficiently.
