Cannot read property 'emit' of null in _http

Cannot read property 'emit' of null in _http_client.js

Version: v6.14.2
Platform: Linux clearnet 4.9.56-21.pvops.qubes.x86_64 deps: update openssl to 1.0.1j #1 SMP Tue Oct 17 23:58:50 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
Subsystem: http

I'm getting the following error on every run of registry-static:

_http_client.js:277
  req.emit('close');
     ^

TypeError: Cannot read property 'emit' of null
    at TLSSocket.socketCloseListener (_http_client.js:277:6)
    at emitOne (events.js:101:20)
    at TLSSocket.emit (events.js:188:7)
    at _handle.close (net.js:509:12)
    at TCP.done [as _onclose] (_tls_wrap.js:332:7)

It's happening reliably for me at 317673 while processing ng2-comps. I haven't tried with an empty output folder yet because it takes me a few days to get that far into the database.
