Re: [Boost-users] Boost SSL handshake(http_server_sync_ssl) : still reachable memory keeps increasing

4 Mar 2022

      I have added some code in on_shutdown to get the session object and free it
explicitly. The same stack is not observed in the valgrind report anymore.
Is this fine? any comments?

    void
    on_shutdown(beast::error_code ec)
    {
        if(ec)
            return fail(ec, "shutdown");

Hi,
I tried the async program as suggested and I still see one of the
stacks where the "still reachable" memory keeps increasing with duration. I
have attached the relevant stack and the program. Sorry I had to resend
this email multiple times due to size limitations. Hopefully this will go
through.
It's entirely possible that OpenSSL caches memory, which would be beyond
the responsibility of Beast or Asio.
I don't see anything controversial in your program.
I see this on stack overflow, but no answers:

Thanks a lot. I will give it a try.

http_server_sync_ssl.cpp
Oh, right. Synchronous APIs have no way to time out. So if the remote
host does not close gracefully (i.e. just slams the connection shut)
then you will be left with a connection object which either has no way
to be destroyed, or has to wait what could be a very long time (up to
2 hours) for the operating system to time out the synchronous read.
Please try the asynchronous example, http_server_async_ssl.cpp and
determine if the problem persists.
Thanks
