Need info regarding delay (16 minutes) in acquiring connection

We have found from the driver log that delay of 16 minutes in getting connection. I would like to understand why the delay? The logs says it is because of service unavailability, Is there any exponential delay introduced by the driver when acquiring connection fails ?

Please provide more information so that i can fix this issue and reduce the delay in getting the connection even when network connection disrupts.
