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".

re: PID values. The long PID values imply that the 64-bit kernel is active so larger PID and TID values are normal
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 !

radisk(8) System Manager's Manual radisk(8)NAME
radisk - Digital Storage Architecture (DSA) disk maintenance program
SYNOPSIS
/sbin/radisk -c LBN length special
/sbin/radisk -e special
/sbin/radisk -n special
/sbin/radisk -r LBN special
/sbin/radisk -s LBN length special
OPTIONS
The following options can be used with radisk: Clears a forced error indicator on the range of specified LBNs. The forced error condition
indicates that the data in the disk block is bad. The disk block is good, but the data can not be read without getting an error detection
code (EDC) error. This option causes the forced error condition to be removed. After the forced error indicator is cleared, the EDC error
is not reported nor will the data be marked as bad. The data should be restored either by manual methods or with the restore command. The
radisk command affects the integrity of the data on a disk and should be followed by a file system restore if data is affected. Sets the
exclusive access attribute associated with the specified disk. This attribute is provided by multihost controllers to restrict access to a
disk to one host. The radisk command returns a failure status if the disk is already exclusively associated with another host or the
underlying controller does not provide multihost support. If the command is issued to a disk that is currently mounted and the command
fails, the disk is no longer on line to this host. For this reason the -e option should not be issued to a disk that is mounted. Clears
the exclusive access attribute associated with the specified disk. If the controller provides multihost support and the exclusive access
attribute is not set for a particular disk, it would be possible for the disk to be accessed by more than one host. The radisk command
returns a failure status if the disk is not currently and exclusively associated with this host or the underlying controller does not pro-
vide multihost support. Replaces a block on the disk specified by LBN. See RESTRICTIONS. Starts a scan for bad blocks on the specified
area on a disk. Bad blocks are disk blocks that have data transfer errors to the extent that they cannot be relied on. When a bad block
is found, it is replaced and the bad block's LBN is reported. The LBN specified with the -s option can be 0 to indicate the first block in
the specified partition. If 0 is specified, however, the program starts searching from the first block of the partition. The -s option
accepts any valid partition on the disk. This allows any partition to be scanned without scanning the entire disk and ensures that the
specified partition is free of bad blocks. As an example, /dev/rdisk/dsk0h indicates the h partition of the boot disk, 0.
DESCRIPTION
The radisk Digital Storage Architecture (DSA) disk maintenance program allows you to maintain DSA disk devices. The radisk command must be
used on unmounted disk partitions to ensure correct results.
The LBN is a decimal number that represents the logical block number as reported in the errorlog file. The LBN is the actual disk block
number starting from the beginning of the disk.
The length is a decimal number that indicates how many (512 byte) blocks to process. The length specified can be -1 to indicate the last
block of the specified partition.
The special file specified is used with -c, -e, -n, and -r options and indicates an unmounted c partition of a character device special
file.
RESTRICTIONS
You must be in single-user mode when using the -c, -r, and -s options of the radisk program. If you are in multiuser mode, radisk hangs
the system and cannot be killed. If this happens, you must reboot.
The -r option is supported only with those DSA disks which use host-initiated dynamic bad block replacement.
The -e and -n options are only supported on controllers that provide multi-host support. These options are only supported on HSC Version
5.00 or later.
ERRORS
The radisk program generates messages when the user is not privileged, when the LBN is not in the specified partition, and when the length
exceeds the size of the partition.
