We noticed a big increase in user CPU utilization on our MX servers since Sep 2nd sa-update. On a typical day we process over 2 million emails on our mail cluster.

The issue was an old version of __SARE_URI_VISIT_US in 70_sare_uri1.cf

If you have a version of 70_sare_uri1.cf installed and it's dated 2005, it will cause a loop on certain (possibly all) recent Facebook mails due to an unbounded regex in a body rule.

The SARE rules are all stale and deprecated, they should no longer be used.
