266 hits in 7 days at the time of bug report, excluding havana jobs (which
are susceptible to lock wait timeout errors anyway because of fixes not
backportable from icehouse)
Build failure rate: 20.6%
Hits in gate queue: 26
Failures in gate queue: 1
Notes:
1) Occurrences and failure rate in gate queue are lower because most of the
failure happen with the full job, which is not yet voting.
2) Even if failure rate is generally low, a lock wait timeout should be
always considered an error, regardless of the outcome of the build job.
3) A detailed look at the logs reveals a pattern similar to bug 1283522,
whose fingerprint is being matched. It seems the semaphore lock is ignored, but
lockutils lacks the necessary logging to reveal whether a semaphore has been
released or not; more investigations are in progress.
