pulse is down, causing cascading failures


(Webtools :: Pulse, defect, P1, blocker)



(Not tracked)



(Reporter: dustin, Unassigned)



Pulse appears to be overloaded and mostly failing. I can't really load the admin UI but it did show me a graph with two nodes down and one overloaded.

This is causing Taskcluster to fail.

I've contacted cloudampq support with an urgent request. Their admin console is not responsive. Our nodes are having high memory utilization two of them appear to be unresponsive. I've rebooted them this did not address the problem.

From Cloudampq support
Your consumer count has gone from 110 to almost up to a 1000 and the same for queues, this is the reason for the increased memory usage which stopped the servers from processing messages.

They restarted the nodes and messages started being processed again.

Trees are closed until the backlog is caught up, will defer to ciduty to decide when to reopen
I will schedule a postmortem for this outage
We should investigate the root cause of the increase in volume
Are they valid consumers/messages
Is the current server configuration we have at cloudampq valid or do we need to change it to accommodate our volume
