Additional Information

Root Cause:
The flow control setting of the network card on the server was misconfigured to value of 3 instead of 0, the default value which stops the flow control. In short flow control was enabled when the setting is more than 1 and disabled when the value is set to 0.So when this setting was set to 0, that's when there were no packet drops and all the web-services started coming up successfully.

Flow Control - It is a parameter that allows the user to enable or disable the receipt or transmission of PAUSE frames. PAUSE frames enable the adapter and the switch to control the transmit rate. The side that is receiving the PAUSE frame temporarily stops transmitting.
