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.
