A couple things cause this. One is that the mongrel is overloaded with
too many connections so it can't accept any more.
If there's isn't that much load on the server, then it's more likely
that you are leaking an open file here or there. If you are doing code
like this:
a = open("blah.txt")
a.write("hi")
a.close()
Then you are probably leaking files. Look for that, and then translate
to the block form:
open("blah.txt") {|a| a.write("hi") }
That's probably the #1 mistake people make from other languages.
