FortiOS 4.0 MR2 Patch 3 Issues

In my experience, as well as other people who post to the Fortinet forums the 4.2.3 patch causes significant problems when accessing websites. The reason for this appears to be the IPS engine. Disabling IPS on a firewall rule restores normal speed, however you lose IPS functionality which is of course not desirable.

Stay tune for updates on this one.

Got an issue with SSL-VPN radius authentication.
Had to rollback to 4.2.2 and all went good again.

Heck, what's going on in Fortinet QA department? Don't they test their ROMs before releasing them anymore?

I'm rather flabergasted by the string of faulty firmwares released in the last quarter really.

To say I'm disappointed would be a mild euphemism.

Boys in Fortinet should slow down! A lot of new features every major release, but luck of quality. I have encountered too many problems lately.

I simply reverted back to patch 2 as our web traffic was crawling after I upgraded firmware.

Upgraded my 60c to 4.2.3 and CPU is at 95+% with SSL-VPN turned on. Without it, it drops to 0-4%.

i had a memory problem with my 80cm. kicked into conserve mode constantly. i had to revert back to the previous build to restore my functionality. this is the second build that jacked my memory causing conserve mode problems. the previous one was last summer. the rep i spoke to said they were getting reports of others with memory problems.
