Hi Jakub, David,

We repro the issue on the server side using this client command:
$ wrk -b2.2.2.2 -t4 -c1000 -d5 --timeout 5s
https://2.2.2.3:20443/256000b.img

Port 20443 is configured with:
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256;
sendfile off;


Important:
1. Couldn't repro with files smaller than 40KB.
2. Couldn't repro with "sendfile on;"

In addition, we collected the vmcore (forced by panic_on_warn), it can
be downloaded from here:

Regards,
Tariq
