Reading about task in the manual page for proc(5)
For attributes that are shared by all threads, the con‐
tents for each of the files under the task/[tid] subdirectories
will be the same as in the corresponding file in the parent
/proc/[pid] directory (e.g., in a multithreaded process, all of
the task/[tid]/cwd files will have the same value as the
/proc/[pid]/cwd file in the parent directory, since all of the
threads in a process share a working directory).
The fds is another example of a resource that is shared across tasks so all
of them will be duplicated in procfs. The reason you are seeing different
values for different tasks is most likely because your application is
opening new sockets while you are running the commands.
