My observation so far is that the file descriptors are released in the
slower rate then the creation rate.  For some reason, the file
descriptor are not released immediately.  In the long term, the file
descriptors of the closed sockets are released completely according to
'lsof'.  Release rate is a problem though - I will keep investigating.
