df, mv, date, rmdir segfaults, other commands acting funny

    Hello all,

    A few nights ago my server lost power during a heavy thunderstorm and
    it's never been the same since. I should also mention that one of my
    non-critical partitions on my HD was full.

    The first problem is that it wouldn't boot up properly. It starts with
    ppp not being turned on due to a fork failure.

    Trying to investigate my startup problem, my best theory is that some
    fundamental module must have been corrupted. Here are my symptoms:

    1) Running ps -aux reveals several zombied processes: ls, rm, touch,
    mkdir
    2) Bash is working, however some of my environment variables (the
    colours specifically) don't get set.
    3) Several commands that have the -h option error saying that -h is an
    invalid option, even though it obviously is.
    4) date, df, mv, rmdir all segfault, 100% of the time.
    5) This leads to several other programs not working properly, including
    locate, updatedb and apt.

    Other than that - everything else seems to be working alright. PHP,
    Apache, postgres all start up and run fine.

    I'm an experienced programmer, but only a moderate Linux user - if I
    could get some advice on how to trace back my problems to a single
    function or process request I can nip this issue in the bud.

    Thanks in advance!
