Environment

  • vCenter 8.x
  • ESXi 8.x

Cause

The mount requests from the ESXi host are being re-transmitted. Connections to port 3260 is getting re-transmitted to 43985

Resolution

  1. Run the below command on the ESXi host to collect the packet captures after initiating mount request to check if the mount requests are getting re-transmitted.
    pktcap-uw --vmk vmkX --dir 2 -o /tmp/vmkX.pcapng

  2. Review the packet capture using WireShark.



  3. If NFS mount requests are being re-transmitted, ensure the required ports are open between the ESXi host and the NFS server. Engage backup vendor for further information regarding the issue.
