LKBEN10860: An application on your terminal server get killed by the windows operating system.
Symptom
You might have a problem with the desktop heap size limit in windows.
Cause
none
Solution
The following Registry key can be used to set the value higher. It will set the Windows key to the text:
%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,8192,512 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=Off MaxRequestThreads=16
This can be done with the registry file below which is hard to read because it is a REG_EXPAND_SZ.
In fact, it just changes the secand value of SharedSection to 8192. The default is 3072 and this might be to small for certain applications. In our case we could start the application 7 Times on a terminal server. Debug traces would always lead to a stack overflow which was very misleading! After this setting we had no more problems with the system.
The desktop heap size can be made visible with the dheapmon tools.
On the terminal server you need to view your session 0 and your local session! For more information on dheapmon, search on the word in the windows knowledgebase. The output looks like this for session 0:

Please note that this setting does help for bad software. It will help when your Desktop Heap Size has reached its limit.
