we enabled "LogoffCheckerStartupDelayInSeconds" and set to 10 seconds.
That seems to have improved things somewhat, apps certainly now not logging off
Thanks again to everyone for your helpful input!

I think you'll find that it's related to the logon process, where if the timing 
is wrong and the app doesn't start up quick enough, the system may log the 
session off. There are two registry keys that you can try. 
IntervalsForLogoffCheck or LogoffCheckerStartupDelayInSeconds. Below is an 
excerpt from my adm template. LogoffCheckerStartupDelayInSeconds is a common 
requirement in XenApp 6 environments.


CATEGORY "MACHINE Custom Settings"
CATEGORY "Citrix XenApp Settings"
CATEGORY "XenApp Session Settings"

POLICY !!CitrixIntervalsForLogoffCheck
EXPLAIN !!CitrixIntervalsForLogoffCheckExplain
KEYNAME "SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI"
PART "This setting has been superseded by the 
LogoffCheckerStartupDelayInSeconds setting." TEXT
PART "IntervalsForLogoffCheck" NUMERIC REQUIRED SPIN 1000
VALUENAME "IntervalsForLogoffCheck"
MAX 12000
MIN 3000

POLICY !!CitrixLogoffCheckerStartupDelayInSeconds
EXPLAIN !!CitrixLogoffCheckerStartupDelayInSecondsExplain
KEYNAME "SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI"
PART "LogoffCheckerStartupDelayInSeconds" NUMERIC REQUIRED SPIN 10
VALUENAME "LogoffCheckerStartupDelayInSeconds"
MAX 6000


CitrixIntervalsForLogoffCheck="IntervalsForLogoffCheck - Wait for processes to 
start during login process"
CitrixIntervalsForLogoffCheckExplain="When launching certain published 
applications, the session was logged off before the application was started. 
The issue occurred if both session and application startup took several 
seconds. This fix adds support for a registry setting to configure the time 
allotted before checking to determine if the session should be logged out 
because no more user processes exist.\n\nThis setting has been superseded by 
the LogoffCheckerStartupDelayInSeconds setting.\n\nRequires the Rollup hotfix 
for MF XP 1.0 SP4 at minimum."
CitrixLogoffCheckerStartupDelayInSeconds="LogoffCheckerStartupDelayInSeconds - 
Prevent a published app from immediately closing on launch"
CitrixLogoffCheckerStartupDelayInSecondsExplain="This setting allows you to set 
the length of time a client session waits for an application to start before 
disconnecting. The length of time, in seconds, to wait for application start. 
Enter the delay time in seconds, up to 100 minutes (6000 
seconds).\n\nRequires:\n- Hotfix Rollup Pack 5 for Presentation Server 4.0 for 
Windows 2000 Server.\n- Hotfix Rollup Pack 3 for XenApp 5.0 and Presentation 
Server 4.5 for Windows Server 2003.\n- Works with base release of XenApp 5.0 on 
Windows Server 2008R1.\n- Works with base release of XenApp 6.0 on Windows 
Server 2008R2."

This is a race condition experienced with Appsense EM & Citrix.

Disable EM and test again.

I believe there is a workaround i just haven't had the time to test it.
