Re: Increase non-interactive heap space on Windows

[Ben Hochstedler]

Only 512KB is allocated for non-interactive processes’ heap on Windows (NT, 2000, XP, 2003, etc).  Too many processes in QDX will eat it up, and occassionally you’ll see the following if another non-GUI process is started & not enough heap space is available:

Quote:

Application popup: cmd.exe – Application Error : The application failed to initialize properly (0xc0000142). Click on OK to terminate the application.

The command can be any command that is run under a non-interactive service (a service that is not marked as being able to interactive with the Windows desktop).

Workarounds:

Mark QDX service as being able to interactive with desktop (will use the desktop heap space for which there’s by default 4MB)

Consolidate threads into fewer processes

Quick instructions for option c:

In Registry Editor, locate the following registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerSubSystems

Open the “Windows” value, locate the SharedSection parameter string in the Value field, and change the 3rd & 4th parameters from “512,512” to “2048” (a 4th parameter is actual invalid and is ignored if present).

Close the Registry Editor and reboot the system.
