## Symptoms

- * VSX cluster members (Active and Standby) show high CPU usage on Firewall Kernel (FWK) processes.

* Many blocking messages are found in both cluster members *$CPDIR/log/cpd.elg* log file, for example:  

  ```
  Warning:cp_timed_blocker_handler: A handler [0xf7701550] blocked for 31 seconds.
  ```

  <br />

* Running `perf top` command shows over 50% on CPU utilization in `_raw_spin_trylock`.

* Running `top -H` command shows multiple `pidof cpd` processes.

## Cause

The CPD process is causing a high CPU usage.
