Thank you brothers...!!!!! 
My transaction confirmed and completed

Thank you for your help.

Hi,
I have done one transaction yesterday it stuck. no confirmation till 12 hrs. When i tried to increase  fee by right clicking and selecting increase transaction fee option it saying Fee bump error - increasing transaction fee failed (Transaction had descendents in mempool). I dont know what to do further. Its kind of emergency and i am relying on this money for one emergency. That would be very helpful if some one can help me.

I am using bicoin core latest version v0.15.0.1

Transaction fee: -0.00458054 BTC
Net amount: -0.19467174 BTC
Transaction ID: cd3daf6abcd12762ff3f2a287e69e6f25a5a5aed418ca542814451b63ebd5fce
Transaction total size: 30415 bytes
Output index: 0

i am ready to pay if anyone could solve this and make it confirm immediately

Thank you
