But those two processes are hanged for another host kernel bug, and this time a very bad one! The first process is in "D" state. If it stays that way, it will never die - and it also means you have had a kernel Oops or something like that - search /var/log/messages on the host and you'll find some text about that, which you should post (search "Oops" and you should find it). Btw, this is a host kernel bug, so you should probably also report it to LKML (post it here also, to get some more answers). Also, could you post "ps -ef" output about this processes, if they are still alive? If not, the Oops text should be enough. > I've sent them kill signals from 1 thru 64 (including, of course, > SIGCONT) and neither process is interested in quitting. > I can't strace to the second process (attach: ptrace(PTRACE_ATTACH, > ...): Operation not permitted) > There is nothing happening on the strace of the first process. I guess that "strace" should even hang on the first process, since it has freezed this bad way. -- Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 ------------------------------------------------------- This SF.Net email is sponsored by: Sybase ASE Linux Express Edition - download now for FREE LinuxWorld Reader's Choice Award Winner for best database on Linux. http://ads.osdn.com/?ad_id=5588&alloc_id=12065&op=click _______________________________________________ User-mode-linux-devel mailing list User-mode-linux-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/user-mode-linux-devel
