The system does not always show violations in request log when post request is large.
Although the violations is handled correctly, it is not reported.
A large post request with many parameters is sent.
Disable learning mode. The internal parameter pb_sampling_high_cpu_load can define what is seen as high CPU load above which sampling does not take place. The default is 60. -- Using a lower value reduces the chances of sampling data. -- Using 0 makes sampling never happen and thus this issue does not occur (this slows down automatic policy building).
