It has something to do with systemd's log thingy.

The error only appears in one place in the syslog-ng source,
in modules/systemd-journal/journal-reader.c:

static inline gboolean
__seek_to_saved_state(JournalReader *self)
{
  JournalReaderState *state =
persist_state_map_entry(self->persist_state, self->persist_handle);
  gint rc = journald_seek_cursor(self->journal, state->cursor);
  persist_state_unmap_entry(self->persist_state, self->persist_handle);
  if (rc != 0)
    {
      msg_warning("Failed to seek to the cursor",
          evt_tag_str("cursor", state->cursor),
          evt_tag_errno("error", errno),
          NULL);
      return __seek_to_head(self);
    }
  journald_next(self->journal);
  return TRUE;
}


First step would appear to be to check systemd's built-in log thingy
