I can post my exact procedure if you like.
It's not just sshd, it turns out; just happened during a rather massive apt-get: Get:51 http://http.us.debian.org stable/main exim 3.36-16 [759kB] Fetched 15.3MB in 30m3s (8507B/s) Preconfiguring packages ... Tried to segfault it so I could get a core file, and got: Tracing thread segfault at address 0x0, ip 0xa0217b6b on the console, but it didn't die (or dump core). Regular kill did cause it to dump core, though. Or maybe it was just taking a really, really long time to dump all that stuff out. Dunno. Boy, my machine is basically totally unusable right now. Yeesh. Several minutes of type ahead and such. Dumping 512MiB to disk (it made two core files) from RAM on a machine with a fully encrypted disk turns out be painful. :-) gdb on the core file, unfortunately, gives nothing useful. Just a (very) long list of things like: #12009 0x00000024 in ?? () #12010 0xc890ba00 in ?? () #12011 0x5489a019 in ?? () So no help there, but if someone wants to provide me with a debugging symbols version, I'll try that. On the off chance that it matters, here's my start command: linux mem=256M ubd0=Debian-3.0r2.ext3 con=null con0=fd:0,fd:1 con1=none eth0=daemon single If people have other things I should try to debug this, I'll be happy to do them. -Robin ------------------------------------------------------- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl _______________________________________________ User-mode-linux-user mailing list User-mode-linux-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/user-mode-linux-user
