I've been seeing a lot of unexplained disk activity (based on my
observation of the drives' LEDs) and CPU system time on one of the
10.4.6 systems here -- dual G5 with 3.5 GB RAM, 2 external FW
drives, and a pair of internal SATAs bound as a software RAID1. I
first tried top, which didn't give any clear leads, then thought
lsof might give me a decent start at figuring out whether this was
mdimport or NAV or some other process. However, invoking /usr/sbin/
lsof as root produces inconsistent results, with one of the
following occurring:
- No processes listed; no error messages
- No processes listed; error message "can't read process table"
- A small but variable number (2-8 or so) of files listed, derived
from 1-3 processes; no error message
- A small but variable number (2-8 or so) of files listed, derived
from 1-3 processes; interspersed "can't read fileglob for . . ."
errors
At no time does it return more than a few lines of data.
As noted, the system's running 10.4.6 (Darwin xxxx 8.6.0 Darwin
Kernel Version 8.6.0: Tue Mar 7 16:58:48 PST 2006;
root:xnu-792.6.70.obj~1/RELEASE_PPC Power Macintosh powerpc), with
anywhere from half to >90% of the RAM in use, but a pagein rate of
0-50/sec.
Is this expected behavior for lsof, and if so is there a
workaround? I hesitate to call it a bug since I'm not that deeply
familiar with OS X internals.
Thanks for any help you can offer.
