$ERR_DBGNOSOCK
610
Unable to attach to remote debug port
The port specified for debugging was already in use when xfServerPlus attempted to launch the runtime or when the runtime attempted to listen on that port. The xfServerPlus session or program execution continues as if debug were not enabled.
This error may be written to the rd.log file when the debugger is running remotely (i.e., in a client/server configuration).
