Could you suggest me where I have done mistake.
check your system carefully. Maybe insufficient energy minimization?
Don't forget to use position restrained MD to relax the system prior to
your production MD run.
I have had no troubles with this POPC system from Dr. Tieleman's website:

Also, check out the talk on "Membrane simulations" from the Gromacs
Workshop 2007:
