Description (partial)


npu_server task crashed when "clear drops" command was issued from CLI.

When issue "clear drops", in very rare occasion, the npu_server will crash due to the drop_data_buffer_pointer which is also accessed by the drop_info_update thread is deallocated by the "clear drop" CLI. This is a timing race condition between these two execution threads.
