Total OS freeze on running the gulp task with 109 SVGs #16

Open marcofranssen opened 8 years ago

marcofranssen commented 8 years ago

Hi,

Our development VM has 4GB of memory and 2CPU assigned at 75% execution cap. We are running the following gulp script to transform our svg to png. However 8 out of 10 times it completely kills the VM. The only solution is to just force a poweroff and reboot.

It is ran on a debian wheezy VM.

I really hope there is someone with a solution for this issue.

gulp.task('svg2png', ['clean-dest', 'build-iconfont'], function () {
      return gulp.src(iconsInput)
          .pipe(svg2png())
          .pipe(gulp.dest(iconOutput));
});

The input are 109 SVGs. Is there a way to make it work without freezing the whole OS?

I have the feeling that for each svg2png conversion a new phantonjs browser is started. My OS runs out of memory and freezes as you can see in my latest output from top, just before the freeze.
