Hello. I am using Magnum 18.0.0.0rc2.dev2 in OPS 2024.01 with Magnum-Cluster- API(0.17.0) from Vexxhost. But I have these errors as:

Ignore error [QueuePool limit of size 1 overflow 50 reached, connection timed out, timeout 30.00 (Background on this error at: https:// sqlalche.me/e/14/3o7r <https://sqlalche.me/e/14/3o7r>)] when syncing up cluster status.: sqlalchemy.exc.TimeoutError: QueuePool limit of size 1 overflow 50 reached, connection timed out, timeout 30.00

Full log is in:

I don't work on Magnum but we have had a bug similar to this in Nova in the past:

in case it could help with investigating further.
