(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 = NULL;
-  long ssl_options = SSL_OP_ENABLE_KTLS;
+  long ssl_options = 0;
   char *ciphers_string = NULL;
 #if !defined(LIBRESSL_VERSION_NUMBER) && (OPENSSL_VERSION_NUMBER >=
0x10100000L)
   int ssl_proto_version = 0;
**


2. run several instances of POST 

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