Huge disk I/O while building

[cnrat]

I tried this docker inside a VirtualBox instance as following.

OS: CentOS 7 x64
Kernel: 5.2.11
CPU: 8 Cores @ 5GHz
Disk: 250G @ Intel 760p SSD

I only made it building to 26% before I noticed my disk I/O gone crazy.

In iotop it showed an unbelievable reading rate at 1.6GB/s kept for nearly 3 hours. All 8 cores had very low load while process hanged in uninterruptible sleep (state D).

Dose any one see this before? Thank you.
