Hi Ronf,
Thank you for your reply. I've checked the CPU on both ends and neither of the boxes are very busy. The CPU usage on the Fortigate is 1% and the Juniper has 91% idle on Slot 0 and 79% idle on slot 1.
I've found another strange thing. I am connecting to my switch stack using the IP address on me0 and this gets disconnected quite often (every minute or so). When I log back in, i see the following message:
warning: This chassis is operating in a non-master role as part of a virtual-chassis (VC) system.
warning: Use of interactive commands should be limited to debugging and VC Port operations.
warning: Full CLI access is provided by the Virtual Chassis Master (VC-M) chassis.
warning: The VC-M can be identified through the show virtual-chassis status command executed at this console.
warning: Please logout and log into the VC-M to use CLI.
And when I look at the virtual-chassis status, it switched from the master to the backup.

Something is going wrong here, but I can't find it..
I also read that I have to set the link speed of the ae interfaces, but that didn't help my error message go away.
When I look at the LACP configuration on my Fortigate router, I get the output below. It says that the LACP speed is slow, but you can see that there is a difference in the actor state of port1 compared to the rest of the members. Port 1 has frame collection and frame distribution disabled.
LACP flags: (A|P)(S|F)(A|I)(I|O)(E|D)(E|D)
(A|P) - LACP mode is Active or Passive
(S|F) - LACP speed is Slow or Fast
(A|I) - Aggregatable or Individual
(I|O) - Port In sync or Out of sync
(E|D) - Frame collection is Enabled or Disabled
(E|D) - Frame distribution is Enabled or Disabled

All ports on the LACP are configured exactly the same on both the Fortigate as the Juniper hardware. Could this be a faulty cable?
