Hi,
We have noticed that some DB calls using Spring JDBC have taken long time to execute , I am confused here whether the time is taken for executing query or for releasing connection to Datasource pool . Below are the logs , can someone please suggest on what could be wrong here ?

( I am new to the forum so apologies if I have posted this to a wrong Forum) .
