Application Sessions waiting on SQL*Net message from client

Hi Team,

Our application Team has reported that they are getting the below error code while executing any queries at the database end. However DB connection is fine:

The error they are getting is: Connection timeout occured.

When check from the DB end:

SQL> select SID,EVENT,P1TEXT,P1,P2TEXT,P2,SECONDS_IN_WAIT/3600 "Time in Mins",wait_time from v$session_wait where event like '%message from client%';

       SID EVENT                          P1TEXT                       P1 P2TEXT                       P2 Time in Mins  WAIT_TIME
