You might have to observe or log a while to see. I have used a simple script to find processes that are using high CPU, where I do a ps -ef every N seconds, and compare them, suppressing lines with 0-1 second CPU used, using some sort, comm -13 and grep. Logging time for each pass is good, too, so you can see who runs what when to drive it up. You may find a looping process right off the bat. It goes something like this:

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)

comm
COMM(1) BSD General Commands Manual COMM(1)NAME
comm -- select or reject lines common to two files
SYNOPSIS
comm [-123i] file1 file2
DESCRIPTION
The comm utility reads file1 and file2, which should be sorted lexically, and produces three text columns as output: lines only in file1;
lines only in file2; and lines in both files.
The filename ``-'' means the standard input.
The following options are available:
-1 Suppress printing of column 1.
-2 Suppress printing of column 2.
-3 Suppress printing of column 3.
-i Case insensitive comparison of lines.
Each column will have a number of tab characters prepended to it equal to the number of lower numbered columns that are being printed. For
example, if column number two is being suppressed, lines printed in column number one will not have any tabs preceding them, and lines
printed in column number three will have one.
The comm utility assumes that the files are lexically sorted; all characters participate in line comparisons.
DIAGNOSTICS
The comm utility exits 0 on success, and >0 if an error occurs.
SEE ALSO cmp(1), diff(1), sort(1), uniq(1)STANDARDS
The comm utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
HISTORY
A comm command appeared in Version 4 AT&T UNIX.
BSD June 6, 1993 BSD
