[err] event_assign called on an already added event 0x84de9e4 (events: 0x0, fd: 0, flags: 0x0)
void connection::listen_write_event() {
 int rc = 0;
 if (fd == -1) return;
 if (is_listening_write) return;
 is_listening_write = 1;
#ifdef DEBUG
   fprintf(stderr,"%d:%08X, LISTEN WRITING\n",fd, (unsigned int)pthread_self());
#endif
 event_del(&_sock_ev_write);
 rc = event_assign(&_sock_ev_write, s->get_evt_base(),
  fd, EV_WRITE,
  server::con_ready_pattern, this);
 if (rc == 0)
  event_add(&_sock_ev_write, NULL);
 else
  syslog( LOG_CRIT, "%d:cannot create write event",fd);
}
i cannot supress the warn even if i put an event base (probably missunderstood the doc)
i declaredÂ
struct event_base * evt_base; as a global
and get it init:
#ifdef DEBUG
 event_enable_debug_mode();
#endif
 evthread_use_pthreads();
 gconf.evt_base = event_base_new();
 if ( gconf.evt_base == NULL ) {
  syslog( LOG_ERR, "cannot allocate base for %s:%d", gconf.ip, gconf.port);
  return 1;
 }
then used it everywhere
to create the bug i connect frenzy to the server using a while true;
Notice: if the program do not close the FD i exhaust the files desc before reaching the bug.
