Looks like a physical device is the only option for that. I figured as much looking at the man page myself. :( Oh well! > Since I'm just cathing up and your question was 1.5 weeks ago, had any luck > since then otherwise? None. And it just crapped itself today again. I'm currently running 4.7-RELEASE-p2. For what it's worth, I configured a 2GB swap file on my largest partition. It doesn't seem to be helping so much right now. :) Also, and this is the first time I've seen this, my nightly mail from Charlie Root contained something of possible interest. It contained 665 lines of "vm_page_cache: attempting to cache busy page". Any ideas what it means and is it related? I cursory search on Google and Google Groups revealed little. It's the first time I've seen it since this started happening, so maybe it's a clue!? Anyway, at this point, I'll probably end up backing up the 260GB+ of junk currently on the machine and will reinstall this coming weekend, configuring enough swap space to catch a crash dump this time. Fun! Of course, once I have done this, it will probably stop dying on me. -- Mark Nipper e-contacts: Computing and Information Services nipsy@tamu.edu Texas A&M University http://arrakis.tamu.edu/nipsy/ College Station, TX 77843-3142 AIM: texasnipsy ICQ: 66971617 (979)575-3193 Yahoo: texasnipsy -----BEGIN GEEK CODE BLOCK----- GG/IT d- s++:+ a-- C++$ UBL+++$ P--->+++ L+++$ E--- W++ N+ o K++ w(---) O++ M V(--) PS+++(+) PE(--) Y+ PGP++(+) t 5 X R tv b+++ DI+(++) D+ G e h r++ y+(**) ------END GEEK CODE BLOCK------ ---begin random quote of the moment--- "Give us this day our daily Faith, but deliver us, dear God, from Belief." -- Aldous Huxley, _Island_, 1962S ----end random quote of the moment---- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
