On 70% of the swift-proxy servers, the load average increased a lot at about the same time.

It does not seem to be related to trafic change. We can see an abnormal level of Software Interrupts.

Investigations are still ongoing

It seems it comes from a kernel bug. We will deploy a kernel upgrade.

The upgraded kernel fix the issue. We are deploying it on all servers.
