Hi. I was doing some silly stress-tests like the following

while [ 1 = 1 ]
do
         time sh ./convert-all.sh
done

convert-all.sh does this:

for a in *
do
convert -scale 90% $a ../out/$a &
done
wait

In other words, it starts a number of concurrent 
ImageMagick 'convert' processes. At the moment I am trying to run 720 
converts simultaneously.

If I start the test after a fresh reboot, I get tons of errors like the 
following:

ELF interpreter /libexec/ld-elf.so.1 not found
Abort trap

but if I interrupt the test, and re-start it, things go ahead as normal. 
Unfortuntately after 16 or so runs of convert-all.sh, the ELF errors 
reappear.

Who has any idea why this is?

Hardware is a sun fire v20z with 2 opteron 250 CPUs and 4G mem. I am using 
5.4-STABLE from last week with a GENERIC kernel, except for the addition 
of SMP.

Cheers
Michiel
