lmdb v 24 requires manual resizing/growing during it's normal function Zano core is purely async so it's not easy to prevent all DB txs from starting on lmdb adapter level, because it will lead to random deadlocks in the core due to many high-level cross-thread dependencies. We will rethink this later. Many thanks to @leo-yuriev who helped us to discover these issues!
