This latest time it died with the swap command failure I mentioned before. And this command shows the permission problem (2) that I reported to Eric. The full output, from command entry to death, is as follows. The second '#', near the end, is my shell prompt returning to me, microseconds before death. # /bin/fuser -n tcp 5553 Cannot stat file /proc/1675/fd/3: Permission denied Cannot stat file /proc/1675/fd/4: Permission denied Cannot stat file /proc/1675/fd/5: Permission denied Cannot stat file /proc/1675/fd/6: Permission denied Cannot stat file /proc/1675/fd/7: Permission denied Cannot stat file /proc/2852/fd/6: Permission denied Cannot stat file /proc/2852/fd/7: Permission denied Cannot stat file /proc/2853/fd/6: Permission denied Cannot stat file /proc/2853/fd/7: Permission denied Cannot stat file /proc/2854/fd/6: Permission denied Cannot stat file /proc/2854/fd/7: Permission denied Cannot stat file /proc/2855/fd/6: Permission denied Cannot stat file /proc/2855/fd/7: Permission denied Cannot stat file /proc/2866/fd/0: Permission denied Cannot stat file /proc/2866/fd/1: Permission denied Cannot stat file /proc/2867/fd/0: Permission denied Cannot stat file /proc/2867/fd/1: Permission denied Cannot stat file /proc/2868/fd/0: Permission denied Cannot stat file /proc/2868/fd/1: Permission denied Cannot stat file /proc/2869/fd/0: Permission denied Cannot stat file /proc/2869/fd/1: Permission denied Cannot stat file /proc/2897/fd/3: Permission denied Cannot stat file /proc/2902/fd/4: Permission denied Cannot stat file /proc/2911/fd/3: Permission denied Cannot stat file /proc/2914/fd/1: Permission denied Cannot stat file /proc/2921/fd/3: Permission denied Cannot stat file /proc/2921/fd/5: Permission denied Cannot stat file /proc/2921/fd/6: Permission denied Cannot stat file /proc/3512/fd/3: Permission denied Cannot stat file /proc/3512/fd/4: Permission denied Cannot stat file /proc/3512/fd/6: Permission denied Cannot stat file /proc/3512/fd/7: Permission denied Cannot stat file /proc/3537/fd/3: Permission denied Cannot stat file /proc/3537/fd/4: Permission denied Cannot stat file /proc/3645/fd/3: Permission denied Cannot stat file /proc/3676/fd/4: Permission denied Cannot stat file /proc/3676/fd/5: Permission denied Cannot stat file /proc/3676/fd/7: Permission denied Cannot stat file /proc/3680/fd/0: Permission denied Cannot stat file /proc/3680/fd/2: Permission denied Cannot stat file /proc/3680/fd/3: Permission denied Cannot stat file /proc/3680/fd/4: Permission denied Cannot stat file /proc/3700/fd/3: Permission denied Cannot stat file /proc/3735/fd/1: Permission denied Cannot stat file /proc/3735/fd/2: Permission denied Cannot stat file /proc/3735/fd/4: Permission denied Cannot stat file /proc/3735/fd/5: Permission denied Cannot stat file /proc/3735/fd/7: Permission denied Cannot stat file /proc/3946/fd/3: Permission denied Cannot stat file /proc/3946/fd/4: Permission denied Cannot stat file /proc/3946/fd/5: Permission denied Cannot stat file /proc/3946/fd/6: Permission denied Cannot stat file /proc/3948/fd/3: Permission denied Cannot stat file /proc/3948/fd/4: Permission denied Cannot stat file /proc/3948/fd/5: Permission denied Cannot stat file /proc/3948/fd/7: Permission denied Cannot stat file /proc/3948/fd/8: Permission denied Cannot stat file /proc/3948/fd/9: Permission denied Cannot stat file /proc/3948/fd/10: Permission denied Cannot stat file /proc/3948/fd/11: Permission denied Cannot stat file /proc/3948/fd/12: Permission denied Cannot stat file /proc/3948/fd/13: Permission denied Cannot stat file /proc/3975/fd/0: Permission denied Cannot stat file /proc/3984/fd/9: Permission denied Cannot stat file /proc/3984/fd/10: Permission denied Cannot stat file /proc/4020/fd/4: Permission denied # swapper[0]: bugcheck! 0 [1] Modules linked in: Pid: 0, CPU 3, comm: swapper psr : 0000101008026038 ifs : 8000000000000288 ip : [] Not tainted -- I won't rest till it's the best ...
