Thanks for all. Finally found the issue. Think it should be a network delay. The load balancer was configured in such a way to send the ping requests for every 3 secs. But it didn't happened and it was irregular. And it sent all the delayed pings at a time. I think it should be the cause. Am I right? Please confirm.
