Orion Bootnodes do not work properly

[eum602]

Orion bootnodes are not working properly. Scenario 1: Orion Node "A" points to Orion Node "a" as bootnode. Orion Node "B" points to Orion Node "a" as bootnode.

If orion node "A" tries to send a message to orion node "B" then the message is NOT received by If orion node "A" sends a message to orion bootnode "a" then it is received. Node "B".

======================== Scenario 2: Orion Node "A" points to Orion Node "a" and Orion Node "b" as bootnodes.

If Orion Node "A" sends a message to Orion bootnode "a" then the message is received. If Orion Node "A" sends a message to Orion bootnode "b" then the message is NOT received.

====================== If explained scenarios are tested with different bootnodes other than the 4 bootnodes in the Lacchain architecture, then all works as expected.

Problem was partially solved by migrating bootnode keys to new virtual machines(with the same ip). The problem is still persisiting in one bootnode VM.

There are many logs that are apparently related to this issue on the following path: "/" ; those logs indicates that the is an insufficient memory RAM.

I suggest the following: At the conceptual level:

• Each instance that wishes to make private transactions may do so as long as it additionally installs an orion node in a new VM.

Requirements:

• the Orion VM: 1CPU; 2GB RAM
• VM Besu: 2CPU; 8GB RAM
• Orion ports: 4040, 4444 (the latter should only listen to the ip of the besu node).

development in ansible:

• Create the deployment scripts to instantiate a new orion node.
• Modify the deployment scripts to instantiate a new besu node.
  • As input, the ip of the orion node could be requested so that during the besu deployment it points to the orion ip.
  • The other required input is the nodeKey.pub of the orion node.

Indicate in the readme the sequence of steps to:

• deploy orion
• display besu
• modify the orion firewall rule so that it listens on port 4444 to the besu intance, and 4040 port is opened to anyone.
