[katello-devel] Load Balancer options

[Mike McCune]

Wrote up a wiki page where I wanted to explore if switching our Apache 
ProxyBalancer options to something other than the default would help 
when we had blocking IO.  You can see some test code that helps 
reproduce the issue.  We can use this in the future to help pick a 
better solution

the short conclusion is:

the fact that long running IO in Ruby 1.8.7 blocks the entire Ruby 
process is pretty lame and all 3 algorithms offered by Apache make no 
real difference in detecting and dealing with 'stuck' thin processes.

For now I think we are going to leave it alone until we can explore 
other options like JRuby and Ruby 1.9.X
