Freetrade, once my server adds a ton of addresses to the node list from other nodes, it hangs for more than 20 seconds.
My log shows a dozen lines of adding xx addresses and then hangs.
My auto cycler script detects this hang and restarts.
My Maxconnections is 800 so I will now try 700 to see if it hangs.
EDIT: Must have been my script. [20 second checks are too fast to detect debug log changes when the node is churning]. I'm setting my auto cycler script to 3 minute crash detects because it could take some time to churn to and from other nodes.
