Symptoms:
	PHCO_30438:
	( SR:8606328942 CR:JAGae90079 )
	Over a period of time, the cimserver process might run out
	of file descriptors. This would cause failures when
	attempting to query the cimserver through a WBEM client. One
	common failure would be authentication failures.

	( SR:8606328943 CR:JAGae90080 )
	The IO Tree Provider prints messages such as -
	"0/1/1/0:No device information associated with this
	hardware path", on the console. These messages are not
	indicative of an error and should not be printed on the
	console.

	( SR:8606347205 CR:JAGaf08029 )
	The IO Tree Provider might report some platform management
	devices, such as "Core I/O Adapter", "IPMI Controller" and
	"Acpi Hardware", as PCI devices when queried for instances
	of HPUX_PCIDevice by a WBEM client.

Defect Description:
	PHCO_30438:
	( SR:8606328942 CR:JAGae90079 )
	The IO Tree WBEM Provider causes a gradual leak of file
	descriptors. This can happen when a WBEM client repeatedly
	queries for PCI slot and card information, which are handled
	by the IO Tree Provider. Since the number of file
	descriptors allowable to a process is limited, the parent
	cimserver process will eventually not be able to open any
	files. At that point, the only solution is to restart the
	cimserver.

	Resolution:
	The fix is to ensure that the IO Tree Provider always closes
	any files it opens, before returning control to the
	cimserver. This must be done for every request.

	( SR:8606328943 CR:JAGae90080 )
	The IO Tree Provider has some debug print statements that
	are enabled in the non-debug version of the provider.

	Resolution:
	The resolution is to ensure that all debug print statements
	are enabled only in the debug version of the provider.

	( SR:8606347205 CR:JAGaf08029 )
	On some platforms, platform management devices such as
	"Core I/O Adapter", "IPMI Controller" and "ACPI Hardware"
	are reported by commands such as ioscan, even though they
	cannot be directly accessed by the OS. The IO Tree Provider
	reports such devices as instances of the HPUX_PCIDevice
	class and returns incorrect values for some of the
	properties.

	Resolution:
	The fix is to filter out devices that are not claimed by PCI
	drivers in the IO Tree Provider. These devices will not be
	reported as instances of the HPUX_PCIDevice class.

Enhancement:
	No
