Hi dear misc-Mailinglist,
After I repaired my IBM-Webserver I did a little "burn-in"-Test and
noticed a "freeze" (no reaction..) if I do the followring (using bsd.mp).
Login as root (local): top -s 1
Login as user and switch to root (via SSH using 4096Bit DSA-Key): john
/etc/master.passwd
Login as user and switch to root (via SSH using 4096Bit DSA-Key): sh
burn-in.sh
-- burn-in.sh --
#!/bin/ksh
cd /tmp
ssh-keygen -b 512 -t dsa -f dsa -N ''
rm dsa*
ssh-keygen -b 1024 -t dsa -f dsa -N ''
rm dsa*
ssh-keygen -b 2048 -t dsa -f dsa -N ''
rm dsa*
ssh-keygen -b 3072 -t dsa -f dsa -N ''
rm dsa*
ssh-keygen -b 4096 -t dsa -f dsa -N ''
rm dsa*
ssh-keygen -b 8192 -t dsa -f dsa -N ''
rm dsa*
ssh-keygen -b 16384-t dsa -f dsa -N ''
rm dsa*
------------
It's the only situation where the Server freeze.
There's NO hardware error, no power down and no entry at the Diag-logs
provided by the BIOS.
OpenBSD 3.6 (+patches) wont react, ssh dies and even local acces isn't
possible (I see still the "top"-screen (freezed ofcourse)).

WARNING: / was not properly unmounted
I upgraded even the BIOS because I thought it's maybe a Bug of the BIOS
but it isn't. Is it possible that the sheduler spends too much CPU-Time to
these processes so that the box freezes?
I hope somebody is maybe able to verify my results.
Kind regards,
Sebastian
