ab is erroring out with apr_socket_recv: Connection refused (61)

I am testing eventlet out, and I am getting this error:

~>ab -n 10 -c 1 http://localhost:8090/
This is ApacheBench, Version 2.3 <$Revision: 655654 $>

Benchmarking localhost (be patient)...apr_socket_recv: Connection reset by peer (54)
Total of 2 requests completed

The website works at localhost:8090/ and returns 200 OK.

I had the same issue with tomcat, again the website worked fine.

What could the issue be?

New versions of Apache have fixed the issue. Download the latest package from https://archive.apache.org/dist/:

$ wget https://archive.apache.org/dist/httpd/httpd-2.3.16-beta.tar.bz2
$ tar jxvf httpd-2.3.16-beta.tar.bz2 
$ cd httpd-2.3.16-beta
$ ./configure

You only have to build ab, which is located in the support folder.

$ cd support
$ make
...
$ ./ab -n 10 -c 1 http://localhost:8090/

Another related bug that is still present in ab (apache-2.4.29) is that it takes just the first result from getaddrinfo. It's probably this bug that is mentioned by Jürgen Strobel in a comment. Let's say you have /etc/hosts that goes like this:

127.0.0.1   localhost.localdomain   localhost
::1     localhost.localdomain   localhost

The first result returned by getaddrinfo for localhost is ::1. So ab tries to connect over IPv6 and fails. The workaround is to use 127.0.0.1: ab -n 10 127.0.0.1/. Or reorder the lines. Though, in my case it says:

Benchmarking localhost (be patient)...apr_socket_recv: Connection refused (111)

add the -r option which means Don't exit on socket receive errors. At times you might change the default ulimit size value. ab -r -n 10 -c 1 http://localhost:8090/
