The IntervalsForLogoffCheck value has been available for years Andy, but
rarely comes up. They "recently" phased it out for
LogoffCheckerStartupDelayInSeconds, which more often than not is a default
requirement for XenApp 6 environments.


Glad it helped James.

we enabled "LogoffCheckerStartupDelayInSeconds" and set to 10 seconds.

That seems to have improved things somewhat, apps certainly now not logging

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"

The issue occurred if both session and application startup took several
seconds. This fix adds support for a registry setting to configure the time

hotfix for MF XP 1.0 SP4 at minimum."

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

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.
