That probably means that there wasn't a dump there. You normally don't need to force it. > Is there anywhere else I need to specify the dump device? No, that's all. > Do I need to specify the full path instead of just the device? Ah, yes, of course. There's no way for the dump routines to guess a path. Try /dev/ad2s1b. > I've not had a kernel panic before, so I'm pretty much a newbie when > it comes to that aspect. I have no custom code added to the kernel. > Any help will be *greatly* appreciated. A couple of other points: 1. Your swap partition needs to be at least fractionally larger than your real memory. The dump routines write a dump and a header. 2. You need enough space for the dump on /var/crash. Otherwise it won't save the dump. Greg -- When replying to this message, please copy the original recipients.
