I have two nodes, a private one and a public one. After importing a snapshot in my private node, I’m finishing to sync it connecting to my public node, but it's worker crashes after a few minutes. After that, it even rejects a new connection from the public node using connect address <private_node_id>:9732, and I have to relaunch the private node, and sometimes even run again trust peer <public_node_id> and trust address <public_node_id>:9732.

In the case it's important, I'm running both nodes in AWS, using t3a.medium and EBS.

Error in the private node:
