  The SAP error message /ISDFPS/SYNC_MONITOR016 Packet loss too high for PING to &1 indicates that there is a significant packet loss when trying to ping a specific host (represented by &1). This can lead to communication issues between systems, particularly in scenarios involving SAP Landscape Management or other distributed SAP systems.
  Causes:

  Firewall or Security Settings: Firewalls or security settings may be blocking or throttling ICMP packets (used by the ping command).

  Check Network Connectivity: Use tools like traceroute or ping to diagnose where the packet loss is occurring. This can help identify if the issue is local or on the network path.
  Inspect Network Hardware: Check the status of routers, switches, and other network devices for errors or alerts. Replace or repair any faulty hardware.
  Review Firewall Settings: Ensure that firewalls are configured to allow ICMP traffic and that there are no rules that might be causing packet loss.
  Monitor Server Performance: Check the performance metrics of the target server to see if it is under heavy load. If so, consider optimizing the server or scaling resources.
  Check Physical Connections: Inspect cables and connections for damage or loose connections. Replace any faulty cables.
