[blfs-support] du on / produces errors from /proc
Does anybody know what causes the following:- du: cannot access '/proc/602/task/602/fd/4': No such file or directory du: cannot access '/proc/602/task/602/fdinfo/4': No such file or directory du: cannot access '/proc/602/fd/4': No such file or directory du: cannot access '/proc/602/fdinfo/4': No such file or directory Can they be ignored? I don't appear to have a problem. Richard -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
