I too cannot manage to get a crash dump, neither classic style nor minidump. Nor can I get it to work with DDB, there seems to be a problem with DDB and my Geom mirror. Kris recommended I up kmem_size which I have done (twice now) and since the last time I upped it, the machine has not crashed again (yet?). For the moment, I'm hoping things are stable. In /boot/loader.conf, I currently have the following: vm.kmem_size=1G vm.kmem_size_max=1G vm.kmem_size_scale=2 and in my kernel conf file I have: options KVA_PAGES=512 Here's what top says currently: last pid: 57367; load averages: 0.56, 0.54, 0.61 up 2+10:16:57 15:50:55 407 processes: 6 running, 378 sleeping, 2 zombie, 21 waiting CPU states: 0.1% user, 0.0% nice, 2.3% system, 0.7% interrupt, 97.0% idle Mem: 1309M Active, 1291M Inact, 497M Wired, 155M Cache, 199M Buf, 7408K Free Swap: 9541M Total, 1628K Used, 9540M Free Is this a heavily loaded machine? It's using a lot of memory, but it's mostly idle. I have 2 sticks of double-sided memory (4gig total) in the box. The SuperMicro documentation recommends using single sided sticks for 6 or more sticks. I feel for you John, I've lost many nights sleep in the last couple weeks trying to understand why this production box was crashing. I was really surprised to see this start happening, normally my freebsd boxes have uptimes in terms of years, not hours. Michael Grant
