    Subject2.1.97-VGER killing random processes under heavy load ? signals ?

    Hi all...

    I have some trouble with my SparcIPX... This has been happening to me
    for quite a long time (at least since the 2.1.89-VGER snapshot which was
    around a month or so ago), but only recently was I able to somewhat
    characterise a little.

    In short : when the loads goes up a little, (2.5+) some processes are
    randomly killed, sometimes. This began to be quite more visible since I
    wrote a little keyboard light blinker based on the system load (I was
    getting jealous of LCDproc <grin />). This program queues SIGALRM's every
    125ms or so, and reads /proc/loadavg every second.
    When the load is around 2-3, loadlights gets frequently killed, forcing me
    to wrap this daemon-wouldbe into a wrapper shell script (and
    simultaneously having a (custom built) "nanny" cron script). Such random
    deaths happened in the past, but became quite more obvious on a
    signal-intensive program -- may be this could be the reason ?

    (base machine is a RH4.2, now using egcs-1.02 and kernel 2.1.9x)

    nikopol# cat /proc/cpuinfo > attached-cpuinfo.txt ; \
    ldconfig -v > attached-ldconfig.txt



    I'm currently setting up a (networkless, so that'll take a few floppy
    swaps) similarly-versioned i386 to try to reproduce the problem, but in
    the meantime, has anyone any clue of what could be in cause ?

    Thanks in advance !
