Did you see any issues with FortiClient and El Capitan prior to the 499 build?
We don't know for certain it is FortiClient, however, the crashes occur with FortiClient loaded and then goes away when it is removed. The FortiClient kext is the last to be loaded. Certainly it could be something else, but as I said, our El Capitan users never saw this prior to installing and using FortiClient. Crashdump is below.
