Comment:

 Since longclaw changed to sbws 1.1.0+84.g3033421, and as commented in
 https://trac.torproject.org/projects/tor/ticket/30905#comment:8, the
 number of failures has been around 1000.
 So the high number of failures were not due to measurement failures, but
 bad counting of the actual errors.
 I think we can close this ticket.

Comment (by teor):

 We're not seeing very many network errors (4%), so this bug mainly wastes
 CPU time.

 longclaw's most recent vote shows that 90% of measurement attempts fail:
 recent_measurement_failure_count is 299K, and
 recent_measurement_attempt_count is 327K.

 We should work out why sbws is doing so many failing measurements.
