Do these lockups have *anyhting* in common? All running the same app?
All on desktops? All the users are using the same mapped home drive? Are
there servers that have never had a lockup? Just grasping at straws
here...

Subject: [THIN] How To Diagnose Session Lockups ??
Hi All - this is a bit of a generalised question, but I am after
some kind of guide/document/steps on how to diagnose "frozen" citrix
sessions. We have a reasonable amount of user sessions that essentially
"lock up / freeze" and the only thing that can be done is to reset the
session and have the user log back in again. The clients are on the
same 100MB switched LAN as the Citrix servers, and the clients vary from
Compaq T20 & Neoware thin clients, to NT4/2000/XP laptops/desktops
running ICA clients. The servers are a mix of 2000 SP4 + Win2k3 SP1 -
all running Presentation Server 4. We have checked the obvious things
like server performance/errors, network performance/errors, swapped out
local clients, recreated user profiles etc, but because the problem is
random, and affects random users, it is difficult to track a
pattern/cause. The amount of sessions that are affected are
relatively low in relation to the amount of concurrent user sessions
across the environment (approx. 350 concurrent connections each day
across approx. 14 servers - with maybe a handful of session lockups per
week). Any ideas on how this type of problem can be diagnosed would
be appreciated.
