Warp sync failing on fresh DB

[tomusdrw]

I'm running:

• Parity version: v1.8.0-unstable-7ddbc6c-20170906/x86_64-linux-gnu/rustc1.21.0-beta.2
• Operating system: Linux
• And installed: from source

---

Warp sync failed with no apparent reason, and wouldn't continue at all later.

Why did you lose all peers between 13:21:43 and 13:22:13?

@tomusdrw does this still happen? Could use a sync=trace log
