Kernel Panic? Or just a stutter?

[wordmunger]

I had thought I was starting to see kernel panics on my Ti400 (running 10.3.5), and this was confirmed by a Knowledgebase article which includes the following text:

Mac OS X 10.2 introduces automatic kernel panic logging, so you may not see any visual indication of a kernel panic

The Article goes on to describe how to find the kernel panic log on the computer, but I was frequently unable to find one. Strange.

What was happening is that my entire system would freeze up, particularly when loading complex web pages. I could move the mouse around, but no amount of clicking would generate a result. After reinstalling the system (and eventually reverting to 10.3.4), I noticed this same behavior, but sometimes it would only last a second or two, and then everything would start working again. Was this all that was happening when my system was "crashing" before?

Just this morning, I had another "stutter," but after ten or fifteen seconds, it still wouldn't return to normal functioning. I thought about restarting, but then I decided to just leave the computer for a few minutes and see what happened. Amazingly, after a couple minutes, it was working perfectly again.

So it seems that I probably was never experiencing a kernel panic all along, just a "stutter."

Anyone else having this experience? Anyone know of a solution?

I've seen similar things and have simply rebooted after a little bit. I'll wait longer now, but I'd really appreciate a notice that the kernel panic is occurring so at least I'd know what was going on - assuming that's what the problem was. I've also seen the occasional stutter, which might or might not have also been a panic. Dunno. I'm staying on 10.3.5 out of laziness, but I might switch back if it gets worse. So far, not too bad.

They're all "Out of IOVM Space" panics... I have no idea what caused them, and they happen roughly every two weeks or so.

i was talking to my girlfriend online and her comp. froze, so she called me and told me that she had dragged the system X folder into iChat and tried to send it to someone. and then we she tried to restart her comp. it said PANIC (CPU 0) (unable to find driver). what should she do!? she has an iBook 1ghz. thank you!

They're all "Out of IOVM Space" panics... I have no idea what caused them, and they happen roughly every two weeks or so.

Is your hard drive low on space? It sounds like your computer might be running out of "Virtual Memory" - the swapfile on your hard drive which acts as a holder for extra stuff that needs to be put in the RAM but room isn't available for.

If your hard drive is low on space, try freeing up some more space. If not, I don't know what the problem could be, but you might want to do a clean install.
