I am looking at upgrading my estate later this week and I will post the outcome after monitoring for some days. Thanks John Romer.

We upgraded to 8.13.1.1 and it seems to have resolved the issues. We are no longer seeing the consistent dropping of connections.

We isolated the case to being a power-setting issue with the RealTek NIC of one of our Lenovo tiny-pc models, which caused clients to death-reauth hundres of time. But only on Aruba Central apparently. So A different issue then yours it seems.

Hi Rasmus,
I was looking at upgrading to 8.13.1.1 (LRS) as there was a release note about version 8.13.1.1 should resolve the Bug ID AOS-261894. I have a TAC ticket opened with no joy yet.

We are experiencing somethign similar to this. We are running Aruba9240 Controllers, 8.13.1.1(LSR), with Aruba635 AP's. We upgraded last week to see if it solved the issue, but some users are still reporting issues. Let us know your findings.

I would suggest first upgrading to the latest 8.10 patch release since you are on code that is over a year old. There have been a number of bug fixes since then.
