The value returned into the integer mempages by the "hw.physmem" sysctl value in the "ps" program itself has gone negative because you have more than 8TB of memory installed (you don't), all of your tasks_info.resident_size have become similarly corrupt (unlikely), you are using your own "ps" program or "libc" library (more likely). Is this an Intel system or a PPC, and if it's Intel, is this running "ps" as a PPC binary? If so, then we are probably talking about bit endienness confusion in the sysctl() implementation in Rosetta, and if so, this is not something that was intended to work. Note that if you are popen'ing the ps program from a program where you've selected "run under Rosetta" in the Finder in order to force the program to run as a PPC binary, it will preferentially cause child subprograms to also run under Rosetta. The theory is that this would allow starting a subtask that talked to the main task using endiend dependent means, such as shared memory, data structures in files, or privately defined Mach messages. If this is testing for a commercial product intended to run under both PPC and i386, you should either use the "arch" command on the command line, or thin the binary, rather than checking the checkbox in the Finder, in order to avoid this "affinity" behaviour. On a real PPC, this will just work as intended, while on an Inte you should be running the Intel binary preferentially. This email sent to site_archiver(a)lists.apple.com

Re: Looking at a x86_64 kernel dump?
by William Siegrist 17 Mar '10

17 Mar '10

site_archiver(a)lists.apple.com Delivered-To: darwin-kernel(a)lists.apple.com There is a timer that is reset by watchdogtimerd at regular intervals, and if the timer reaches 0, the machine will restart. If that happens in middle of a dump it will still restart and thus interrupt your dump. You can adjust the interval to be longer than the time it takes to dump in: /System/Library/LaunchDaemons/com.apple.watchdogtimerd.plist Also, see the manpage for watchdogtimerd. -Bill On Mar 16, 2010, at 11:31 PM, Alain Renaud wrote: > Thanks all, > > I found the problem.
