OK, you need to add a mutex around anything that

Yikes, I will dig into this.

I misunderstood the way how your code works. After rereading it, I
think I will use it in my program. Thanks.

This is the valgrind --tool=helgrind output. The first part appears
for every connection to the server:

Hey Björn,
multithreading and libevent is a bit tricky (at least it was for me). I
would also suggest to change your design...
I developed a multithreaded websocket server based on libevent a year ago:
My approach was to create a single event base per thread. Each event base
in each thread listen

The posted code compiles on my machine without modifications. Thus I
wonder why you have to do some cleanup.
But the example code fails silently. Perhaps you don't run it with
enough rights to bind to port 443?
Most of the time I access the server with a browser and keep the
reload button pressed.

That piece of code should distribute the incoming connections over the
threads (I want to change that code later to select the thread with
the lowest number of handled connections). If I don't use this code
and use instead
bev = bufferevent_openssl_socket_new(thread_base[0], sock, client_ctx, ...

Given that you have debian, why don't you install valgrind and see what
it says when you run the test?

I now tried setting up locking callbacks. But my programm still
crashes while stress testing.
I've attached the current code and a stack trace from gdb.
I don't know if it's an openssl or libevent related problem, but I
think I set the locking functions up correctly.

I tried to simplify my code as much as possible. You can see the
simplified code and the error message from gdb below.
Every thread has its own event_base. The only access to the
event_bases of the threads is from the event_base_loop of the
corresponding thread and the bufferevent functions in acce

I can't tell without looking at the rest of the program, but are you
sharing one event_base amon
Try JMeter. I believe AB has bugs.

Hello,
I'm trying to write a simple https server which utilizes multiple cpu cores.
I call evthread_use_pthreads() and create several pthreads. My
acceptcb and the thread worker functions are below.
For some simple test cases it works. If I use a tool like apache ab
for a perfomance test, I get so
