What is mean?

2013-01-13 18:33:29; cppcms, warning: Writing response failed:aio::: connection 
hang-up or invalid discriptor tested (cgi_api.cpp:457)

Artyom something wrong with daemon. With daemon true in filebase.ws chat /get 
works and /post not. With false is works. 

Tmp i run the chat like that sudo ./chat -c config.js&

Nop. Works only if 
"daemon" : { "enable" : false }

Any logs? What does it mean does not work? Errors  in log?

I think problem in sql connection. First message going fine and something 
hapens. But log is empty. I dont know what is a problem. Pointer?

void post(std::string const &message)
{
        cppdb::statement stmt;
        stmt = sql() 
            << "INSERT INTO chat(uid,author,css,image,message,date) 
VALUES(?,?,?,?,?,?)" 
            << uid 
            << author_.name
            << author_.css
            << author_.image
            << cppcms::util::escape(message)
            << mktime(&date)
            << cppdb::exec;
        int last_id = stmt.last_insert_id();

cppcms::json::value obj;
        obj["id"] = last_id;
        obj["uid"] = uid;
        obj["author"] = author_.name;
        obj["css"] = author_.css;
        obj["image"] = author_.image;
        obj["message"] = cppcms::util::escape(message);
        obj["date"] = mktime(&date);
        messages_.push_back(obj);
}

cppdb::session &sql()
    {
        if(!sql_->is_open())
            sql_->open(connection_string_);
        return *sql_;
    }

private:
    std::auto_ptr<cppdb::session> sql_;

Funny. All this time it working very well. Today broke.

In localhost all fine. I dont know. I think, server restart is good solution :)

Poblem is:
Catched exception: cppdb::mysql::Lost connection to MySQL server during query
