Enhanced Security Measures in Place: To ensure a safer experience, we’ve implemented additional, temporary security measures for all users.

We've a PA-3050 up and running for over a year now. It is configured with an agregated interface with LACP enabled (mode active, transmission rate Fast). These interfaces are attacheced to a procurve 5406 where the interfaces on the procurve are configured as a trunk of the type lacp.
This was running fine till now. Last 3 days the connection on the aggregated interface was gone for about 10 minutes. During this period the system log is filled with these kind of messages:
lacp-up,ethernet1/1,0,0,general,critical,LACP interface ethernet1/1 moved into AE-group ae1
lacp-up,ethernet1/2,0,0,general,critical,LACP interface ethernet1/2 moved into AE-group ae1
nego-fail,ethernet1/2,0,0,general,critical,LACP interface ethernet1/2 moved out of AE-group ae1
nego-fail,ethernet1/1,0,0,general,critical,LACP interface ethernet1/1 moved out of AE-group ae1
I found this article, and this seems to be the case. (the l2ctrld.log is filled up with these messages). However: I have no idear how to fix this.

First, I would migrate off of Junos version 14.x for anything unless it is JTAC recommended. There are only a couple pieces of hardware that still use this as recommended. All of my hardware is v15.x minimum with most v17.x or higher. PAN 7.1.x is going EOL next year. I would move to 8.1.x ASAP. It appears you are running code versions that are becoming fairly dated. I would not worry about "increased traffic" of LACP active. You aren't running 10/100mbit links. Even then, it probably wouldn't be an issue.

Yeah, I agree with that, let me do it active/active & will update you, it might be a possibility with version 14.1x53 I'm running on the switch.
Thanks for all your help & thoughts.

I also noticed the same problem between Pan 5250 running 8.1.13 and Juniper QFX10002 running JunOS 18.4R2.7
Both Active, Fast. but 1 interface is keep going out of AE group almost 2 to 5 times an hour.

If it's the same interface, I'd start looking at Layer 1. Bad cable?

I have PA 5050 setup as Fast and Nokia device as slow.
This setup works fine since last 4 years.
