Actions #1

The same thing happens on my machine, after some png export. If some patch is available, I could test this for you.

Running:
Ruby 1.8.x
Ubuntu 10.04 LTS

The same on another machine.
CentOS 6.3
Ruby 1.8.7 - latest patchlevel

It uses all four CPU's.

Maybe there could be some Exportoptions, to disable Export to some special formats?

possibly it's important.

this problem occurred on a vps openvz.
same server redmine 2.1(thin+nginx, from user redmine) on a xen vps works fine, without this bug.

Actions #4

As a workaround, you can bundle Redmine without rmagick to disable the PNG export: bundle install --without rmagick. I think that this feature should be removed anyway.

Well the export to PNG is good for meetings. But a PDF would be good enough too.
