following is the procedure to reproduce:

Workaround:

Thanks to Dan McDonald gives the Workaround:

put into a rc3.d script so they run at every zone reboot:

/native/usr/sbin/ndd -set /dev/tcp tcp_max_buf 16777216
/native/usr/sbin/ndd -set /dev/tcp tcp_recv_hiwat 4194304
/native/usr/sbin/ndd -set /dev/tcp tcp_xmit_hiwat 2097152

/native/usr/sbin/ndd -set /dev/udp udp_max_buf 16777216
/native/usr/sbin/ndd -set /dev/udp udp_recv_hiwat 2097152
/native/usr/sbin/ndd -set /dev/udp udp_xmit_hiwat 2097152
