IMHO, this is not normal behavior. My first guess would be that a program has been restored, or a patch applied, and the libC and/or other shared library is not correct.
If I was on site and could look at other things I would recommend many other things - but for now, to remove many many variables in a short amount of time - AND to know if it is spurious or continous I would look at performing a reboot.
BUT!!! The other common cause of issues with libraries going bad, because they are cached in memory is either a disk gone bad (e.g. rootvg) so programs "run" but are in accurate because they cannot get/write to disk (e.g., a partition can run for hours even though it's rootvg is missing (VIOS is offline by accident) - or - that someone has done "rm -rf /..." by accident. So files are removed, but still open (shared libraries) so programs can still run "some".
Program to check: errpt
Code:
errpt | head
re: PID values. The long PID values imply that the 64-bit kernel is active so larger PID and TID values are normal
Code:
errpt -a | more
Code:
errpt -c
If you think the system will survive a reboot, and you can get a window to perform it - it is a serious option. But be careful - if your disk is bad and you cannot (re)boot you must decide beforehand what is worse: no availability or degraded integrity.

How do you reset the values that vmstat displays?
Vmstat displays a running average from the last the system was restarted on the first line, how do you reset these values without restarting the system? (Solaris 8) (3 Replies)
When I exeute vmstat (e.g. vmstat 30 2),
in some machines I get some wierd result as the first line.
like: -117% or 208% for CPU idle percentage.
But the second line is alright.
Could someone explain this please.
Thanks !

devel::refcount
Devel::Refcount(3pm) User Contributed Perl Documentation Devel::Refcount(3pm)NAME
"Devel::Refcount" - obtain the REFCNT value of a referent
SYNOPSIS
use Devel::Refcount qw( refcount );
my $anon = [];
print "Anon ARRAY $anon has " . refcount($anon) . " reference
";
my $otherref = $anon;
print "Anon ARRAY $anon now has " . refcount($anon) . " references
";
DESCRIPTION
This module provides a single function which obtains the reference count of the object being pointed to by the passed reference value.
FUNCTIONS
$count = refcount($ref)
Returns the reference count of the object being pointed to by $ref.
COMPARISON WITH SvREFCNT
This function differs from "Devel::Peek::SvREFCNT" in that SvREFCNT() gives the reference count of the SV object itself that it is passed,
whereas refcount() gives the count of the object being pointed to. This allows it to give the count of any referent (i.e. ARRAY, HASH,
CODE, GLOB and Regexp types) as well.
Consider the following example program:
use Devel::Peek qw( SvREFCNT );
use Devel::Refcount qw( refcount );
sub printcount
{
my $name = shift;
printf "%30s has SvREFCNT=%d, refcount=%d
",
$name, SvREFCNT($_[0]), refcount($_[0]);
}
my $var = [];
printcount 'Initially, $var', $var;
my $othervar = $var;
printcount 'Before CODE ref, $var', $var;
printcount '$othervar', $othervar;
my $code = sub { undef $var };
printcount 'After CODE ref, $var', $var;
printcount '$othervar', $othervar;
This produces the output
Initially, $var has SvREFCNT=1, refcount=1
Before CODE ref, $var has SvREFCNT=1, refcount=2
$othervar has SvREFCNT=1, refcount=2
After CODE ref, $var has SvREFCNT=2, refcount=2
$othervar has SvREFCNT=1, refcount=2
Here, we see that SvREFCNT() counts the number of references to the SV object passed in as the scalar value - the $var or $othervar
respectively, whereas refcount() counts the number of reference values that point to the referent object - the anonymous ARRAY in this
case.
Before the CODE reference is constructed, both $var and $othervar have SvREFCNT() of 1, as they exist only in the current lexical pad. The
anonymous ARRAY has a refcount() of 2, because both $var and $othervar store a reference to it.
After the CODE reference is constructed, the $var variable now has an SvREFCNT() of 2, because it also appears in the lexical pad for the
new anonymous CODE block.
PURE-PERL FALLBACK
An XS implementation of this function is provided, and is used by default. If the XS library cannot be loaded, a fallback implementation in
pure perl using the "B" module is used instead. This will behave identically, but is much slower.
