Issue

  • EMS:

kernel: nblade.execsOverLimit:error]: The number of in-flight requests from client with source IP 10.20.30.40 to destination LIF 10.20.30.50 (Vserver 7) is greater than the maximum number of in-flight requests allowed (128). The client might see degraded performance due to request throttling.

Note: This message has been moved to severity notice in newer patch releases. This reflects that fact that this message may not always be a cause for concern.

  • This message is normal and expected when the Oracle dNFS client is in use. It does not indicate a problem.
  • High latency or a sudden drop in throughput during peak load on NFS clients might be observed, especially linux.
  • Performance impact cannot be attributed to a CPU/Memory/Disk bottleneck on the storage controllers via CLI or monitoring tools

Note: The message was introduced in ONTAP 9.8 but the throttling existed before ONTAP 9.8 so the same considerations apply
