The error also isn’t the same always | 15:26:04 |
| achingbrain | > UnexpectedEOFError: unexpected end of input
This happens when the remote end closes the stream/connection, usually because of a timeout (e.g. the local end isn’t sending data fast enough).
If you’re starting 30x peers in a single process, it’s going to peg the CPU and grind to a halt.
I have modified your test to pass an AbortSignal to the dial operation, and to increase the incoming stream/connection upgrade timeouts, I get to 18 or so running nodes and the node process is at about 275% CPU but no crashes. | 19:06:37 |
