Socket Error While Working

[Behrad]

In my 1.3.1 production environmet I see this error every 5secs while
couchdb is working and no monit, upstart, ... process is monitoring it!

[Mon, 19 May 2014 07:14:08 GMT] [error] [<0.125.0>] {error_report,<0.31.0>,
                        {<0.125.0>,crash_report,
                         [[{initial_call,

 {mochiweb_socket_server,init,['Argument__1']}},
                           {pid,<0.125.0>},
                           {registered_name,[]},
                           {error_info,
                               {exit,eaddrinuse,
                                   [{gen_server,init_it,6},
                                    {proc_lib,init_p_do_apply,3}]}},
                           {ancestors,
                               [couch_secondary_services,couch_server_sup,
                                <0.32.0>]},
                           {messages,[]},
                           {links,[<0.94.0>]},
                           {dictionary,[]},
                           {trap_exit,true},
                           {status,running},
                           {heap_size,1597},
                           {stack_size,24},
                           {reductions,458}],
                          []]}}

​What does it mean? is another CouchDB process being started? or Couchdb is
facing an error while creating a new socket for a client connection?​
