A self-tracking bug.
From VPS whgi.wikidumpparse.eqiad.wmflabs. Occassionally, for a period of a few days at a time, I am unable to connect to databases replicas, receiving errors: ERROR 2026 (HY000): SSL connection error: unknown error number. Then it will fix itself.
Twice this has happened.
- in 2019/4 (approx 3 days)
- in 2019/6/19 - 2019/6/24
- during this period adding --ssl-mode Disabled fixed the problem as in, mysql -h enwiki.analytics.db.svc.eqiad.wmflabs -u u2443 -p --ssl-mode Disabled
Using this task to track more outages, to see if I can find a pattern. It may be local to the machine, not sure.
