Apache Bench test error on OS X: "apr_socket_recv: Connection reset by peer (54)"

Question

I updated my MacBook Pro 13" to Lion a few weeks ago. I just found out that Apache Bench (apache2.2.19) is not working. It always shows this error, no matter what:

apr_socket_recv: Connection reset by peer (54)

I also did a clean install on my Mac Mini and it produced the same error.

How can I fix this?

Answer 1

Note that if you use -r with Apache Bench, it won't exit on errors.

From the documentation:

-r
Don't exit on socket receive errors.

Answer 2

This is due to a bug in the Apache software that's bundled with Lion. A more recent version of Apache (beta) fixes the problem. To fix ab, here are the steps:

1. Download the latest version of Apache

   $ wget http://apache.mirrors.pair.com//httpd/httpd-2.3.16-beta.tar.bz2
   

If 2.3.16 is not available, go to http://apache.mirrors.pair.com/httpd and get the latest

2. Install pcre (you need brew for this)

   $ brew install pcre
   

3. Build Apache

   $ tar xzvf httpd-2.3.16-beta.tar.bz2
   $ cd httpd-2.3.16-beta
   $ ./configure
   $ make
   

4. Overwrite the existing ab with the newly built one

   $ sudo cp support/ab /usr/sbin
   

Answer 3

Using the method of updating ab through homebrew at this link worked for me.

brew install 'https://raw.github.com/simonair/homebrew-dupes/e5177ef4fc82ae5246842e5a544124722c9e975b/ab.rb'
brew test ab

Answer 4

Did you try using: 127.0.0.1 instead of localhost?

Also my ab fails if I don't write url with http:// in front.

Answer 5

I had the same error with Mountain Lion ab v2.3, and was almost ready to install brew and the latest version of ab as instructed by one of the above answers. Before finally going that way I tried just adding the trailing slash.

user$ ab http://dl.cubrid.org
ab: invalid URL
Usage: ab [options] [http[s]://]hostname[:port]/path

In the above message pay attention to the required format of the input URL. Optional components are marked with square brackets, but notice that /path part seems to be not optional. So I assumed that if I'm testing the root domain, I should at least add the trailing slash, which really did the trick! I hope this helps to you, too.

user$ ab dl.cubrid.org/

Answer 6

A few things to test:

• can you try disabling the firewall any seeing if that works?
• enable web sharing and test localhost/ (make sure it works in a browser first)

If neither of those work can you open a terminal and

$ sudo opensnoop

then run the apache bench and post the output of the opensnoop terminal in the question. If none of that works you could try installing macports and then installing apache from there and seeing if that works as a work around(sort of lame).

My Air is on lion but the apache version is different(there was an update recently, have you already installed that?). I was able to verify ab does work for me:
