Apache Question

[Steve]

I'm trying to figure something out with Apache's ab (apache bench).  If I 
do the benchmark on a .html file I get:

# ab -n 1000 http://127.0.0.1/index.html

If I do the same on a .php file (using php 4.06 as a DSO) I get 98 of 100 
failures...  Don't understand this one.  It fails on "length".  Any ideas 
on what this means?  It does the same on a different machine with Apache 
1.3.20 and php 4.0.6 compiled statically into Apache.
