Run 'netstat -lp' or 'ss -lp' to determine what is listening in port 23 when this happens (and is it sbbs?).

By default, the Synchronet ctrl/sockopts.ini file does not enable the REUSEADDR option. Is this option now enabled? If it is, then a second process (e.g. a second invocation of sbbs) could "take over" the port.
