Rebooting doesn't solve the underlying issue, so it is more of a workaround than a cure, and may be erasing information that would lead to an understanding of the problem. Do you have means to capture packets from the problem system? Can you do a test with outgoing http, https, and ssh blocked? It might be interesting to try a linux stealth rootkit process decloaking tool: sandfly-processdecloak <https://www.sandflysecurity.com/blog/linux-stealth-rootkit-process-decloaking-tool-sandfly-processdecloak/> You say you have a second similar system.
