问题描述
我的服务器已经运行了 20 多个小时了。在此期间，我不间断地对服务器进行压力测试。有时会崩溃，有时不会崩溃。我只使用 Asio Asio Only Source Code 来处理我的网络类。
void AsioChannel::AsyncSendData(const std::shared_ptr<Buffer>& packet)
{
sendding_.store(true);
auto self = shared_from_this();
socket_.async_write_some(asio::buffer(packet->peek(),packet->readableBytes()),[self,packet](const std::error_code& err,std::size_t writen)
{
self->AsyncWriteSomeCallback(err,packet,writen);
});
}
void AsioChannel::AsyncWriteSomeCallback(const std::error_code& error,const std::shared_ptr<Buffer>& packet,std::size_t writen)
{
if (error)
{
return;
}
if (writen < packet->readableBytes())
{
packet->retrieve(writen);
AsyncSendData(packet);
}
else
{
if(!waitwriteq_.empty())
{
auto next = waitwriteq_.front();
waitwriteq_.pop();
AsyncSendData(next);
}
else
{
sendding_.store(false);
}
}
}
崩溃堆栈如下

为什么响应会导致崩溃？
- 未使用 Boost
- 在 C++17 模式下使用 g++ 10.2.0 编译
- 运行 GCC10 的 libstdc++ 以支持 C++17 功能
- 在 Red Hat Enterprise Linux Server 7.2 版 (Maipo) 上运行
- 使用
-O2编译的所有内容
