On looking into the internal logs of the server on which forwarder is configured, I could observe that splunkd  is shutting down for every 24 hours, and starting again. Below are the logs before the shut down, 
 09-06-2016 23:15:24.658 -0700 INFO  ShutdownHandler - Shutting down splunkd

 Below are the logs after a restart has been done,

 What could be the reason for Splunkd to stop..And it is happening on a daily basis..What could be the reason behind it??
