Hundreds of nagios alerts about "Command Queue is CRITICAL: 12 dead items", all non-try trees closed.
I ran the ansible script per https://wiki.mozilla.org/ReleaseEngineering/Queue_directories#troubleshooting still getting reports about dead items in #buildduty
Nick broke PTO silence and offered: [15:25] <@nthomas|pto>| I think it’s upload.ffxbld.productdelivery.prod.mozaws.net not responding to ssh connections, in which case it’s a Cloud Services problem, eg oremj [15:25] <@nthomas|pto>| that’s what’s happening on bm52 in use1, at least [15:26] <@nthomas|pto>| opens a connection ok, but never completes all setup work on the session [15:27] <@nthomas|pto>| aka nc works, ssh -v ends with [15:27] <@nthomas|pto>| debug1: Entering interactive session. [15:27] <@nthomas|pto>| debug1: Sending environment. [15:27] <@nthomas|pto>| debug1: Sending env LANG = en_US.UTF-8 [15:27] <@nthomas|pto>| shell request failed on channel 0
UPDATE: I had told philor to close try (a while ago), based on initial symptoms. A minute or two ago oremj told me try looked like it wasn't exhibiting the errors, I confirmed that on one of our buildbot masters, and had try reopened.
the ffxbld host has been fixed. A bunch of defunct sshd processes quickly accumulated, maxing out sshd's process limits. I'll add monitoring for this scenario on Monday.
We had a handful of the following style of error at ~2016-10-02 16:26:08,644 (PT) Another retry of those caused them all to succeed, :philor has reopened trees.
