apachebench aborts with a strange error message

Question

I run a very simple php file on apache. Then I benchmark apache, using

ab -n 10000 -c 5  http://localhost/~me/hello.php?name=Niko

But I get this error message, depending on c (for c=1, things are fine):

apr_socket_connect(): Operation already in progress (37)

I'm using ApacheBench, Version 2.3 on OSX 10.5.7.

The very simple PHP file would be this one:

<h1>Hello <?=$_REQUEST['name']?></h1>

Answer 1

This might be connected with http://www.nabble.com/ab(1)-fix-(Operation-already-in-progress-(37))-td22821642.html.

This might be it. The post says:

fixed in trunk

Changes were significant, so I have no plans to propose for backport to the 2.2.x branch in the short term. With some testing/everyday use in trunk on various platforms, it may be appropriate to backport later.

Well. That means I would have to wait for 2.3 or work straight with the trunk. I'm just doing hobby stuff, so: no thanks.
