err_tcp() aborts a running close with the error received by the core (ERR_RST/ERR_ABRT).  If this interrupts a running close, closing the netconn aborts with an error (resulting in possible netconn/socket leaks if the calling application is not prepared for close failing).

See also bug #46701 for a discussion on this.
