Strange server behavoir with huge spike in system load while number of context switches are small

fr flag

We're seeing strange behavior on 3 of our machines. We're having trouble figuring what's going on under the hood. We're seeing:

1- A significant drop in the number of context switches.

2- A very large increase in the number of file-descriptors that the system is utilizing.

3- Our system load is too high, showing a sudden spike.

Is this workload familiar to anyone?

Our hypervisor is KVM, on a Xeon machine with 128 GB of RAM.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
