I must admit that my first statistical analysis was flawed, and 
furthermore lacked an element of comparison.
So I refined it and created this table, applying the same objective 
meta-analysis criteria to a range of products :

Product            problems   works     total      reliability %

Apache (httpd)     647,000    857,000   1,504,000    81
IIS              6,530,000  5,900,000  12,430,000    47
Tomcat           2,730,000  5,070,000   7,800,000    65
Jboss              967,000  1,050,000   2,017,000    52
Glassfish          125,000    155,000     280,000    55
Windows         37,500,000 44,300,000  81,800,000    54

 From this, we can draw a number of conclusions :
a) there are a lot more Windows users than anything else
b) there are about 5 times more Tomcat users than Apache httpd users
c) Apache httpd is at least 15% more reliable than any servlet server
d) Tomcat is the most reliable servlet server
e) Most IIS users have problems
f) on a price/reliability ratio, Apache httpd and Tomcat win hands down
