NSX Edge Node Status Down and BFD Tunnel Data is Missing

Cause

This issue can occur if NSX Edge dataplane service goes down due to memory leak in certain NSX Edge processes. In this case, certain NSX Edge CLIs may fail with error encountered.

Solution

1. Run admin cli get service dataplane to view the status of service.
2. If status is down, run cli start service dataplane.
3. Once service has started, run the following CLIs to view the CPU and Memory consumption by NSX Edge dataplane module.
4. Get dataplane cpu stats from /var/log/vmware/top-cpu.log and top-mem.log to watch for values going above 60% usage.
