--- Comment #15 from ss3bsd <3226388001@jcom.home.ne.jp> ---
(In reply to ss3bsd from comment #14)

My reproducing procedure for the panic above is:

1. modify wget in ports to use KTLS and build it

work/wget-1.25.0/src/openssl.c:
**
 ssl_init (void)
 {
   SSL_METHOD const *meth =3D NULL;
-  long ssl_options =3D SSL_OP_ENABLE_KTLS;
+  long ssl_options =3D 0;
   char *ciphers_string =3D NULL;
 #if !defined(LIBRESSL_VERSION_NUMBER) && (OPENSSL_VERSION_NUMBER >=3D
0x10100000L)
   int ssl_proto_version =3D 0;
**


2. run several instances of POST=20

 /usr/ports/ftp/wget/work/stage/usr/local/bin/wget --post-file=3DVERY_LARGE=
_FILE
--no-check-certificate -O /dev/null https://A_SERVER_OVER_10GbEther/ &=20
 /usr/ports/ftp/wget/work/stage/usr/local/bin/wget --post-file=3DVERY_LARGE=
_FILE
--no-check-certificate -O /dev/null https://A_SERVER_OVER_10GbEther/ &=20
 /usr/ports/ftp/wget/work/stage/usr/local/bin/wget --post-file=3DVERY_LARGE=
_FILE
--no-check-certificate -O /dev/null https://A_SERVER_OVER_10GbEther/ &=20
 /usr/ports/ftp/wget/work/stage/usr/local/bin/wget --post-file=3DVERY_LARGE=
_FILE
--no-check-certificate -O /dev/null https://A_SERVER_OVER_10GbEther/ &=20
 /usr/ports/ftp/wget/work/stage/usr/local/bin/wget --post-file=3DVERY_LARGE=
_FILE
--no-check-certificate -O /dev/null https://A_SERVER_OVER_10GbEther/ &
