Only one version is installed with 2 init scripts.

I am not sure how you can tell that I have 2 caches running, if by cache
you mean varnish instances then yes. However I get the same result if I
shut one down.


I run 2 instances in the same physical server one located in
/var/varnish1 and the other in /var/varnish2. I also have 2 other
servers in "hot spare mode" hiding behind the hardware loadbalancer
using the same configuration, but no request should hit those unless my
primary goes down.
