Why are our nodes crashing after inserting large number of assets in them? It starts up with a delay, after around 2 000 assets inserted in a node, each new asset is added more slowly, until either node crashes or we stop inserting assets because it takes around 500+ms per asset. However, if we restart adding assets, they are added slowly, like it continues where we left off. Have you faced the same problem, and do you have recommendation for dealing with this?
