Description of problem:
I was using webmagick <http://webmagick.sourceforge.net/> to generate
some webpages from appr. 1000+ digital photos (each 800x600 .jpg and
ca. 90KB). WebMagick is using PerlMagick included with ImageMagick. I
ran it on my 7.3 system with 512MB RAM and 1GB swap, and after appr.
400 pix had been processed, the kernel decided to kill webmagick.
This is from /var/log/messages:

May  1 17:28:08 saturn kernel: Out of Memory: Killed process 24124 (webmagick).

I tried the same on my up2date 7.2 system (it's physically the same
system actually, so RAM and swap are identical), and didn't see any
problem and, what's even more important, it didn't even *touch the
swap space*!

Initially I suspected the new VM in the 2.4.18 kernel, but when I
downgraded ImageMagick to the version which comes with RHL 7.2, ie.


everything works without problems even on the new 2.4.18-3 kernel.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Get and build webmagick
2.invoke it like "webmagick --verbose" using the .webmagickrc from below

Actual Results:  After some time the kernel will kill the process as it ran out of

Expected Results:  The process should terminate normally.

Additional info:

This should be stuck into the file .webmagickrc in the current directory:
