Phenomenon: After closing the lid of a MacBook Pro and waiting for a while before reopening it (for example, after finishing work at the office and bringing the laptop home), the "net.inet.udp.pcbcount" value significantly increases (reaching over 60,000+ at its peak), resulting in an increase in CPU temperature.Seems like udppcb leak.
Viewing method: Enter "sysctl -a | grep pcbcount" in the terminal.
