I was able to reproduce this problem on a freshly installed 13.2-RELEASE with
no custom configuration:
FreeBSD 13.2-RELEASE releng/13.2-n254617-525ecfdad597 GENERIC amd64
FreeBSD clang version 14.0.5 (https://github.com/llvm/llvm-project.git
llvmorg-14.0.5-0-gc12386ae247c)
VT(efifb): resolution 1024x768
CPU: Intel(R) Xeon(R) CPU E5-2697A v4 @ 2.60GHz (2600.12-MHz K8-class CPU)
FWIW, the problem seems to go away if you add the following to
/boot/loader.conf.local and reboot:
net.inet.tcp.soreceive_stream="1"
I haven't done any further investigation...
