In chainmaker-go (aka ChainMaker) before 2.4.0, when making frequent updates to a node's configuration file and restarting this node, concurrent writes by logger.go to a map are mishandled. Creating other logs simultaneously can lead to a read-write conflict and panic.
FISCO BCOS 3.11.0 has an issue with synchronization of the transaction pool that can, for example, be observed when a malicious node (that has modified the codebase to allow a large min_seal_time value) joins a blockchain network.
