PRB: Pooled COM+ Component Stops Responding When You Use IONA Orbix 3.1 CORBA Library (299411)

SYMPTOMS

COM+ components that utilize IONA Orbix 3.1 CORBA library stop responding (hang) if the components are pooled in COM+ and if the minimum pool size is greater than 0 (zero).

CAUSE

Orbix utilizes WinSock in DllMain. However, the MSDN documentation regarding the DllMain function at http://msdn.microsoft.com/library/psdk/winbase/dll_8asu.htm states that using WinSock from DllMain can cause a deadlock.

RESOLUTION

The only known workaround is to configure the minimum pool size to 0 (zero). It is possible that future versions of Orbix will not utilize WinSock in DllMain.

STATUS

Microsoft has confirmed that this is a problem in IONA Orbix 3.1 CORBA Library, but the problem may also exist in other versions of Orbix.
