Code:
require 'rubygems'
require 'net/ssh'
host = 'xxxxxxx.xxxxxx.xxx'
username = 'xxxx'
Net::SSH.start(host, username, :verbose => :debug) do |ssh|
puts ssh.exec!("hostname")
puts ssh.exec!("ls")
end
When running this program it hangs for 30 seconds at four points, as I
have shown below. Note that I have omitted a number of lines.

If I switch to Java 5 on AIX instead, the program runs without problems.
Also, I can run the same program without problems on Windows XP and Java
6 (from Oracle).
Any help in solving this problem would be much appreciated.
