Hi
I am running a DPDK application with virtio driver and ran in to driver rx
lockup issue.
The application seems to be running fine for couple of hours before it
stops receiving packets on the interface. Transmission of packets seems to
work fine on the same interface while reception of packets stop.
Has anyone run in to anything similar?

Following is the environment
Application runnign dpdk-2.2
VM running on KVM hypervisor using VIRTIO driver
