We have configured nginx + haproxy + mongrels [ more than 150
instances].
While it works perfectly fine for small configuration, a larger set of
mongrels - fail completely.
I have attached the configuration file for your reference. Apologies for
the
inconvenience if this is coming into the wrong list.
What fails completely ? HaProxy, Mongrel or Nginx ?
I noticed that 192.168.1.16 for instance had over 50 mongrels assigned
to it. At an average memory usage of 60-80 meg (just after startup)
that is an enormous amount of memory in use (if I understand your
config correctly), is the problem with the underlying server platform?
Possibly swapping, or spending all its time scheduling processes?
