Troy,
Which of the load evaluator rules seems to be the limiting factor? I'm
guessing its memory. If you're running the same application across all
your servers, do the instances of the application on the 19 'bad' servers
have a bigger memory footprint than the application instances on the 1
'magic' server?
We experienced an issue like this where a handful of our servers were
receiving a different anti-virus configuration that was causing each
instance of IE to take a bigger memory footprint than on the other
servers.

[THIN] Citrix Load Evaluator / Total Sessions per Server & Application
Hey all,
We've had a small issue for the past year, and I can't seem to find an
answer about it.
We started a new 4.5 farm this time last year and have an application that
is published & load-managed across 20 servers.
There is a custom load-evaluator is built on these 4 "Assigned Rules":
Application User Load, Load Throttling, Memory Usage, Server User Load.
Overall, this load-evaluator appears to be working well for our userload;
per server and per application.
Except... One server seems to always have about 10-20% more total sessions
then the other 19 servers.
Over thousands of session - the 19 servers will all be within a range of
100 or so total sessions, but this one server will be always at the top of
the list for total sessions by several hundred more sessions for any time
period.
Theoretically - all of these are equal.
At anytime I run a "qfarm /app" (during average workday) - all of my
servers are in the 4500-6000 load range.
In the "Presentation Console" everything is running against this
load-evaluator.
Also, We have Citrix Edgesight collecting data, that looks normal other
than the total session count.
My performance statistics appear fairly normal at anytime we take a look.
The application is installed identically across the 20 servers.
Anyone have any ideas?
Thanks,
Troy
