Hi, I am modifying example echo server for my server. I started to get the attached error, and I suspect I am using buffer incorrectly since error started after a change there. I just changed a line from boost::asio::async_write(socket_, boost::asio::buffer("1^", 3, boost::bind(&session::handle_write, this, boost::asio::placeholders::error)); to boost::asio::async_write(socket_, boost::asio::buffer(replyString, replyString.size()), boost::bind(&session::handle_write, this, boost::asio::placeholders::error)); I generate the replyString to have results from my database query separated with ^ signs (which is used to tokenize the replyString on the client side...) string replyString="1^"; while(res->next()) { replyString+=res->getString("nickname")+"^"; } I checked that replyString.size() is really one more than the final filled position index in replyString. Any ideas, suggestions? TIA, Best regards, Ozgur (Oscar) Ozturk www.DrOzturk.com Phone: +1 (908) DROZGUR i.e, +1 (908) 376-9487
