Hi,


I’m trying to solve a pattern of kernel panics.

G4 Mirror Door Drive:

• OS 10.4.11
• Dual 1.25
• 1.5 GB RAM
• 1 internal drive, 80 GB, available free space 21 GB
• 1 partition


They’re increasing - from every few months to every week.


Might anyone be able to interpret the panic.logs below, to guess at the cause?


I note that the details are nearly identical for the panics of Sept. 4 and today, Sept. 12.

• Can anyone decipher the logs above, to suggest a cause?

_________________________________________________________________________


– Panics seem to have occurred within 1 to 60 seconds of saving ordinary .rtf word documents ... or clicking to close a document (red button at upper left of document window)

– Panics have occurred both online and offline (TenFourFox)

• One (of two) FW 400 ports is non-working

• One (of two) USB 2.0 ports is working but has sloppy fit (cable relaxes to one side)

• One (of one) FW 800 port is working and tight


– Aside from the panics, computer is stable

– Fan is a smooth quiet sound, except on the three or four very hottest summer days

– No new software has been added

– No changes made inside the case, except careful dusting, including the front air intakes

– G4 runs from a high-quality, true sine wave UPS

– Keeps correct date/time
But battery is not later than 2012

– No memory leaks
Watching “Activity Monitor,” especially later in the day

– Keyboard (wired Macally) and wired mouse are about 6 years old ... worn, but comfortable


A close reading of historical crashreporter.log (goes back to 2008) shows frequent “crashdump started” events with previous owner, up to this year.


The “crashdump started” have occurred from once every few weeks, to three times daily -- but without triggering a kernel panic.


These crashdumps are hidden (unless one reads the log in real time).

I’ve been slowly eliminating possible causes, including:

- Disconnected new StarTech USB 2.0 hub

- Synchronized date/time of Brother all-in-one and the desktop
(Brother was showing about 1 minute ahead of desktop time)

- Only turn on Brother all-in-one when needed ... and then don’t shut Brother down til G4 is off
(Turning Brother off while G4 on, was discovered to cause kernel panic every time, in past years, with G4 QuickSilver. Seems to be a flaw in Brother driver)

- Disabled AppleWorks Auto-Save

- Run Maintenance about weekly


All suggestions will be most gratefully appreciated!


Thank you!

If it was happening to the previous owner as well, i can only think of 3 reasons. Dying hard drive, as it's probably the original one, bad ram, or just a b0rked/infected 10.4 install. I'd backup your files sooner than later. From there i'd get a new HD and reinstall fresh. If it still happens then i'd lean towards bad ram or the sockets maybe loosened up.

Cheers
