Hi @pedrofragola,

the logs show the datastore getting overwhelmed. We've seen the same error logs reported in internal environments. There have been a couple of fixes, for example to the feature upgrade controller that reduces its pressure on the datastore.
For further datastore improvements we are waiting on the new Dqlite release.

Could you please try the latest 1.32 release?

Best regards,
Louise
