Suhosin causes server crash for long pages

Hello everyone.
I noticed that the suhosin patch causes a server crash if you write longer pages with the tinymce editor.

I wrote longer content (about 200 lines) and the server did not respond after pressing the save button. Even ssh login took really long, so it fealt like that a script was running in a endless loop.
I removed the suhosin patch with

now saving works again without errors.
Please note that the "with Suhosin-Patch" string in the php version does not disappear after you removed the suhosin package.

Sorry for the double post.
There is the same thread in the evo forum. If someone could delete it it would be great.

There are a ton of filtering options in Suhosin; you’ll need to configure it to allow longer POST/REQUESTs if this is being blocked by your Suhosin configuration settings.

Wow. I found out that the problem did not disappear. It just worked two times. If I modify the page and try to save it, the saving bar does not disappear and Apache2 consumes 100% cpu.

An interessting part is that I use internet explorer for editing. If I use firefox I do not have any problems (tried 10 times).

Modx version 2.1.1-pl

Is action 30 used for saving resources?
