When a socket is bound for IP stack protocols with port == 0, the kernel picks a free port in a specific range and binds it; on Linux, the range can be seen (and modified) with `sysctl net.ipv4.ip_local_port_range` or looking in `/proc/sys/net/ipv4/ip_local_port_range`. This defaults to 32768:60999. When binding explicit ports (for tests), don't use a port number from that range, or there will be flaky tests as periodically that port will already be in use from another test. This renumbers all the JS clustering tests I found binding in that range to be beneath that range; I checked the code to ensure the new port wasn't already in use.
