Comment 1 Ernesto Puerta 2019-11-22 12:20:34 UTC 
It looks like the pool deletion succeeded. At least I couldn't find any trace of it, and have repeated creation & deletion after that without issue.

Based on the exception above, it looks like the issue is not in the Pool delete, but in the Pool listing, which does not expect a Pool be deleted while being listed (race condition). I tried to gather more logs from that date, but they were rotated and removed.

I've also tried to reproduce this issue by massively creating & deleting pools simultaneously from CLI & dashboard, and couldn't reproduce it.

I'll decrease its severity, as:
* Pools are actually deleted.
* No high impact on users and simple workaround exists (a page refresh fixes the issue).
* Pool deletion is a very rare workflow, which makes this issue even less impacting.
* Can't be reproduced (so far).

Let's leave this open but with low severity and/or move it to 4.1.

Thanks Ernesto.

After setting mon_allow_pool_delete, I am able to delete  Pools without any exception.
