PMDB Client shutdown results in epoll error

[NikhilReddy-2]

If PMDB Client has finished its execution and terminates then we get the following epoll error

 <11042993.414332931:warn:LeaseApp_pmdbSe:epoll_handle_del_complete@330> epoll_ctl(epm_fd=18, eph_fd=35, EPOLL_CTL_DEL): Bad file descriptor
 <11042993.414358470:warn:LeaseApp_pmdbSe:epoll_mgr_reap_destroy_list@436> epoll_handle_del_complete(eph=0x95bcc8): Bad file descriptor

This behavior is reproducible in the leaseApplication branch by starting the PMDB Servers and sending any request from the client side. When the client finishes executing, the above error appears in the PMDB Server logs.
