I have done all this but still no accounting seems to happen.
The reason why I am interested now is that since installing OS 10.0.4 things seem to be much more sluggish and I would like to see if I can get any clues as to what is causing this......or do you have better ideas to pin-point that type of problem?
Well, it definitely doesn't seem to want to work; accton appears to work okay (tried my own program to call acct() directly, which didn't error out). A check of the kernel, 'nm /mach_kernel | grep acct' shows the accounting calls are there. It just doesn't seem to trap the end of processes to write out to the accounting file.
