Continuous PARSE_ERROR and HTTP_REQ_BEGIN_ERR messages on 5508 Controller

Hi All,

 

I am getting a continuous stream of messages like the ones below on my 5508 WLC:

We have an SSID for guest Wifi Access with Layer 3 as Passthrough and WebAuth is Customized Login Page is login.html. This login.html is simply a button which users must confirm a button to say they accept T's & C's and the click on a connect button - simple and straightforward - and it works. We have no wired guests. Client MACs seen in error messages always connected to the guest network, not to the corporate wlan.

 

It's a single, standalone controller deployment, no other wlcs on the network.

 

Code version: 8.5.140.0

APs: many of 1602s and 2802s

 

Thanks!

I have read that comment, so I tried enable sleeping clients feature already, but didn't helped for me. (session idle timer is disabled)

Current logs from WLC:

However I wrote bad informations yesterday, there is L3 authentication, not only an accept button.
