AEM JDBC Connection issue

We are facing wait timeout exceptions while connecting to JDBC database and it happens intermittently. It is happening when only when there is lot of idle time in the night.

 

Exception details :


{​​​​"errorType":"SQL Exception Occured","appName":"Custom-Service","responseMessage":"The last packet successfully received from the server was 52,364,564 milliseconds ago.  The last packet sent successfully to the server was 52,364,564 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.","responseCode":500}​​​​  

 

JDBC config:

jdbc.driver.class="com.mysql.jdbc.Driver"
jdbc.connection.uri="jdbc:mysql://url"
jdbc.validation.query=""
datasource.svc.properties=[""]
default.readonly=B"false"
default.autocommit=B"true"
pool.max.wait.msec=L"100000"
pool.size=L"100000"

 

We tried by increasing wait timeout but still for some users it is failing on higher environments. We also tried with 'autoReconnect=true', but that is also not fixed the issue. Thanks in advance.
