Pt 8.53 'Suspected session affinity issue' messages

Hello,

We recently upgraded to Peopletools 8.53 and I'm seeing the following messages in the servlet logs. I didn't find anything on it in MOS. Could anyone tell me if the is an issue, and if so how to fix it,  or if it can be ignored? We are not using single signon.
