[tor-relays] Refusing to apply consensus diff

[Logforme]

I run the non-exit relay 855BC2DABE24C861CD887DB9B2E950424B49FC34

Two days now I've seen this in my log file:

Jun 05 06:25:02.000 [warn] Refusing to apply consensus diff because the 
base consensus doesn't match the digest as found in the consensus diff 
header.
Jun 05 06:25:02.000 [warn] Expected:

Jun 05 06:25:02.000 [warn] Could not apply consensus diff received from 
server '128.31.0.34:9131'

(Repeated for 204.13.164.118, 131.188.40.189, 154.35.175.225, 
194.109.206.212, 171.25.193.9, 199.58.81.140)

First time I assumed it was just a glitch. Now I'm wondering if there is 
something I should do on my side?
