Not that it should matter, as walking through /proc/* could do same, but... 3.1.15-3. I have no idea what procps were installed at the beginning of February or in the December. Until crash 'ps ax' does not cause problem. Only 'axH', which descends to /task/ subdirectories, crashes. usermap:~# dpkg -l procps Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description +++-==========================-==========================-==================================================================== ii procps 3.1.15-3 The /proc file system utilities usermap:~# Petr Vandrovec
