I have a problem with my AIX 5.3. Recently my unix shows a high cpu utilization with sar or topas.
I need to find what I have to do to solve this problem, in fact, I don't know what is my problem.
I had the same problem with another AIX 5.3 running the same application. The %sys and %user normally shows 45 (user) and 21 (sys) average. I don't know what happened, but the performance decreased and my %usr shows 21 and %sys 50. With a reboot the server came back with normal load and good performance. I don't want to reboot my other server without knowing my problem.
Please, help me to find what process is consuming too much %SYS (see attachments).

There is a script which processes the incoming files from a particular directory and sleeps if it doesnt find any. Currently, i have been told that eventhough there are no files to process, the CPU utilization is very high. An independent evaluation by advisory specialist has found this script does... (2 Replies)
Hi,
I am working on a solaris app processor and the vsh goes high from time to time. I have executed various ps commands and switches and have found that it looks like the rlogind daemon is terminating vsh and not cleaning up after itself. There are also something like 10 zombies hanging around... (2 Replies)

reboot
reboot(2) System Calls Manual reboot(2)NAME
reboot - Reboots system or halts processor
SYNOPSIS
#include <sys/reboot.h>
void reboot( int howto );
PARAMETERS
Specifies a mask of options.
DESCRIPTION
The reboot() function restarts the system. The startup is automatic and brings up /vmunix in the normal, nonmaintenance mode. The calling
process must have superuser privilege to run this function successfully. However, a reboot is invoked automatically in the event of unre-
coverable system failures.
The following options, defined in the sys/reboot.h include file are passed to the new kernel or the new bootstrap and init programs. They
are supplied as values to the howto parameter. The default, causing the system to reboot in its usual fashion. Dump kernel memory before
rebooting; see the savecore command for more information. The processor is simply halted; no reboot takes place. The disks are not sync'd
before the processor is halted or rebooted. Normally, the disks are sync'd (see the sync() command) before the processor is halted or
rebooted. Because the disks are not sync'd with the RB_NOSYNC option, loss of data may result from using it.
When no options are given (that is, RB_AUTOBOOT is used), the system is rebooted from file vmunix in the root file system of unit 0 (zero)
of a disk chosen in a processor-specific way. (see the fsck command).
RETURN VALUES
If successful, this call does not return. Otherwise, a -1 is returned and errno is set to indicate the error.
ERRORS
If the reboot() function fails, errno may be set to the following value: The calling process does not have appropriate privilege.
