Hi team,

In a standalone environment R77.30 with lates hotfix we have observed a huge amount of this message "cmi_execute_ex: Failed to execute the pattern matcher!" in var/log/messages.

We have check the related SK64162 but we did not find any solution. 

Waiting for your response.

Thank you.

If I recall, this may show up if you haven't updated IPS signatures recently.
Have you done this?
