Symptoms:
	PHKL_30398:
	( SR:8606339504 CR:JAGaf00433 )
	System panics with "data page fault" if Kernel
	Instrumentation (KI) tracing is enabled and the system
	reads a symbolic link to a very long (1024 or more
	characters) pathname using NFS Version 3 protocol.
	The stack trace may look similar to the following:
		panic+0x60
		report_trap_or_int_and_panic+0x5c
		trap+0xf58
		$RDB_trap_patch+0x30
		strlen+0xc
		ki_rfscall+0x300
		rfscall+0x47c
		rfs3call+0x78
		nfs3_readlink+0x144
		readlink+0xb8
		syscall+0x6ec
		$syscallrtn+0x0

	PHKL_28052:
	( SR:8606248778 CR:JAGae15175 )
	Glance/UX incorrectly attributes the information about
	processes running in a non-default processor set (PSET)
	to Process Resource Manager (PRM) group zero (PRM_SYS).

Defect Description:
	PHKL_30398:
	( SR:8606339504 CR:JAGaf00433 )
	The maximum pathname in HP-UX is limited to 1024 characters.
	Linux has a larger limit and NFS Version 3 exposes it.
	Calculating the size of a pathname KI code assumes that the
	pathname pointer obtained from the NFS code is valid. This
	assumption is invalid in a heterogeneous NFS environment.

	Resolution:
	Do not calculate the pathname size. Use the size provided
	by the NFS Version 3 server in symbolic link attributes.

	PHKL_28052:
	( SR:8606248778 CR:JAGae15175 )
	Glance/UX interprets Kernel Instrumentation (KI) Fair
	Share Scheduler (FSS) ID of zero as PRM_SYS. KI FSS ID of
	a process running in a non-default PSET is set to zero.
	It should be -1.

	Resolution:
	Set KI FSS ID of a process in a non-default PSET to -1.
	On versions of Glance/UX prior to C.03.55, the -1 is not
	handled correctly causing the data about any non-default
	PSET process to appear in the last application group.

Enhancement:
	No
