Can anyone confirm this or tell me what is going on? why does this crash a 10.4 machine but not Linux.

I do drivers, so I had a bit of a kernel crash debugging setup handy. The program crashed my G5 w/10.4.2 as well. The last messages to the console were: (default pager): [KERNEL]: no space in available paging segments (default pager): [KERNEL]: no space in available paging segments disk0s10: I/O error. disk0s10: I/O timeout. disk0s10: I/O timeout. Memory access exception(1,0,0) Entering system dump routine The crash has a stack like this: (gdb) bt #0 0x000acfa0 in memcpy_nop_if_32bit () #1 0x000ab598 in copyinmsg () #2 0x002741ac in sysctl_procargs () #3 0x002724d4 in kern_sysctl () #4 0x00271ac8 in __sysctl () #5 0x002a7a94 in unix_syscall () #6 0x000abcb0 in shandler () #7 0x41414141 in ?? () I don't have more info than this because I don't have a debug kernel handy for 10.4.2. You should file a bug so that Apple can fix it. It should be easy for them to reproduce. The issues with top have been pointed out before, but they have not been addressed as far as I know. Filing a bug against them might help to get them fixed. As to why it does not crash linux -- linux has been a 64-bit OS for nearly a decade, and they have the rough edges polished off. Tiger is only months old. If you need a ppc64 machine for running large memory jobs, you might be better off with linux. At least the IBM XL* compilers are available in 64-bit versions for linux.
