Not a lot of info to work with ...
Have you tried checking the actual load on the device ? Was there a spike or is this constant ?
Try running an ACC report on the timeframe when you saw this message and try to identify what application is causing the load or where it is originating from. Are there any core-file present on the system ?
In some cases this can be expected when your device is reaching it's limitation and you want to consider an upgrade. However, sometimes this can be related to an attack in which case you are advised to configure zone protection and add DoS policy.
you have enabled the option "Enable Log on High DP load". This will spawn log entries each time the dataplane has high CPU usage:
you can verify the daplane usage from the CLI by issuing this command:
> show running resource-monitor Resource monitoring sampling data (per second): CPU load sampling by group: flow_lookup : 0% flow_fastpath : 0% flow_slowpath : 0% flow_forwarding : 0% flow_mgmt : 0% flow_ctrl : 0% nac_result : 0% flow_np : 0% dfa_result : 0% module_internal : 0% aho_result : 0% zip_result : 0% pktlog_forwarding : 0% lwm : 0% flow_host : 0% CPU load (%) during last 60 seconds: core 0 1 2 3 4 5 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
"Enable Log on High DP load" is really bad name for this checkbox :)
It should be "Write Log entry on High DP load" or something similar.
Before explaining most people think "Enable Log on High DP load" means "Keep on logging even if DP load is high".
