Max Limit Peers

[ccamaleon5]

Problem

When the node reaches the maximum connection limit (by default 25), it begins to disconnect. This affects performance while the node is disconnecting from the other peers.

Solution

Our recommendation for these cases is to limit connections only to bootnodes, which can be achieved as follows:
In the start-pantheon.sh file located in the / lacchain folder add the flag
--permissions-nodes-config-file-enabled

With which the file would look like this:

#! / bin / bash
LOG4J_CONFIGURATION_FILE=/root/lacchain/log.xml pantheon --data-path /root/lacchain/data --genesis-file=/root/lacchain/data/genesis.json --network-id 648529 --permissions-nodes- config-file-enabled --permissions-nodes-contract-enabled --permissions-nodes-contract-address=0x0000000000000000000000000000000000009999 --config-file=/root/lacchain/config.toml

Additionally in the permissions_config.toml file located in the /lacchain/data folder add the bootnodes located in config.toml
´ nodes-whitelist = [ bootnodes list from config.toml ]´

Finally restart the besu service
service pantheon restart

Smart contracts will be created to limit the connection between the different nodes.

Maybe this should be reported upstream.
