@maravapalli(priya): Which version of the JLink OB firmware is on your nRF51 Dongle? You should use v5.10n, which can be downloaded here. You also need to use Wireshark v1.10.x, here is the link to the newest compatible version, i.e. v1.10.14.

In order to downgrade the JLink OB FW on your nRF51 dongle youu'll need to follow the steps below

1. Start JLink.exe with the nRF51 DK/Dongle connected to your computer
2. Enter the following command, exec invalidatefw , to invalidate the J-Link Firmware. This will promt you to upgrade the firmware, press “Yes”
3. Navigate to C:\Program Files (x86)\SEGGER\JLink_V510n, open the commandline in this folder and enter the following nrfjprog command
                nrfjprog --jdll JLinkARM.dll --readcode delete_me.hex
4. You are then promted to update the firmware again, press “Yes”. 
5. The nRF51 DK/Dongle is now using the Segger J-Link v5.10n firmware. If you use nrfjprog afterwards you must not upgrade the J-Link OB firmware if you are promted, i.e. press “No”. Otherwise you have to repeat the steps above.

Well hard to suggest. I had problems in the past with the dongle, it seems more stable on nRF51 DK (dongle gets really hot but it might be unrelated and just my feeling about stability). I would change PC and nRF5x board if possible, maybe that will help. And indeed Nordic sniffer is just "cheap" variant, useful for hobbyists but if you develop some serious commercial product with BLE you could consider some specialized analyzer/sniffer in hundreds/thousands USD range.

I am unable to capture a screenshot since the program just exits abruptly after few seconds. I am using windows platform. My nRF1 dongle sniffer software is 1.0.1 , JLinkARM.dll 5.12g, wireshark -1.10.3 ,python- 2.7.8

Not saying that "logs" are needed, screenshots will do the job for the beginning. What platform you use, on what HW the sniffer FW runs etc.?

How can I capture logs with master emulator. I am unable to sniff and capture logs at the same time with master emulator. I have the sniffer report about 25 devices and it exits unexpectedly.

any detail on what it means "crashes"? What you were doing before? What is visible in command line interface before/after the crash? Or do you mean that Wireshark running on top of BLE Sniffer exe "crashes"?
