HTTP A/V scanning breaks web requests - it's back

We confirmed with Fortinet today that a bug that was fixed in 4.1.6 apparently exists in 4.2.x. It is scheduled to be fixed (again) in 4.2.6.

Here is the original problem from March 2010. It's not a good thing that this was fixed a year ago and is still around in newer builds of the 4.2 branch.

** Update **

Due to 4.2.6 being a quick fix for the split tcp handshake the bug fix will be included in 4.2.7.

FortiOS 4.2.4 Released

We have had 4.2.4 running on some of our test systems for the past 24 hours with no adverse affects. Specifically CPU usage is staying within normal levels. I will also test this on the FWF 60C platform over the weekend.
Please post your feedback after you try it out.
