After installing a central policy on a ProxySG running SGOS 6.5, the CPU monitor is showing CPU utilization up to 90% in the policy evaluation.
This issue occurs when there are one or more syntax errors in the policy. This results in the policy ticket becoming invalid and resulting in a lot of policy re-evaluation causing high CPU utilization. In high-traffic ProxySG deployments, it will stay in this state until the error has been corrected.
This issue has been resolved in SGOS 6.5.7.6.
