in reply to ssh output is partial when using fork manager

Twenty Questions

Further to salva's reply, try experimenting separately with number of nodes, and length of timeout. You may discover there is a relationship. If there is any variation, try plotting number of nodes and length of timeout to get a successful run.

Try looking for problem nodes, by splitting the list into halves, or removing 5 or 10 different nodes each time. You may discover that there are one or two specific nodes that get hung up, but only with a large number of nodes (so it could be network traffic congestion, and poor recovery to/from certain nodes).

What happens to process memory when node count goes up? (Perhaps there's a memory leak/retention you aren't expecting.)

What happens if you run this from different host nodes? Especially, hosts not on the same end router as the original host?

Do you have a different large pool of target nodes, other than the original? How does it perform compared to the original?

Is there anything else you can vary?
