PG-15.6: timeout parameters erroring out

Hello team,

We unabled the postgres timeout parameters in the postgresql.conf file

*idle_in_transaction_session_timeout = '1min'idle_session_timeout = '5min'*

other way also, like below

*idle_in_transaction_session_timeout = 60000idle_session_timeout = 300000*

we see these errors reporting in the logs after we enabled those parameters
*log:*

Is there any know issue/bug with these paramters, can someone help me to
get this worked since our app idle connections are getting pilled up and
reaching max connections.

I really appreciate your help. Thank you.
