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

Why do you assume that "tomcat works" is not included in the "tomcat
problems" result?
+tomcat +problems -works -> 1,830,000 results.
+tomcat -problems +works -> 227,000
227/(227+1830) -> 11% Reliability ... :-)
of course this statement is as un-serious as yours :-)

And no, Tomcat is not reliable at all, it's more kinda toy for bored
developers such as me.

A statistical answer :
- searching Google for "tomcat problems" gives approximately 2,730,000
links.
- searching Google for "Tomcat works" gives 5,070,000 links.
- 2,730,000 + 5,070,000 = 7,800,000 links
- 5,070,000 / 7,800,000 = 0.65
65% reliability is not bad for a free product.
