System Information
Lubuntu 16.04 Intel HD 5500
Ram 4GB

Blender Version
Broken: ( 2.78c e92f235283, 2.78.4 253281f9d6)
Worked: (none)

Short description of error

Exact steps for others to reproduce the error
When I try to render the file attached to the message, Blender renders, but hangs when calculating the second part made by Freestyle. Drains every resource of the PC becomes impossible to manage, I waited some time the term but never got to see the rendering completed.

Works in Windows 10 home edition. This was on 4.2Ghz 6-core CPU 5820k. Freestyle is single threaded, so it's interesting why your whole computer slowed down.

Hi, I tried again today but to no avail, Blender runs out of resources of my PC, the cursor does not move, nothing works not even the esc key to stop,

Good morning, I wanted to add some more information.

This is where hangs in the rendering process.

Freestyle is highly un-optimized for me Blender drained 10gb of ram because you only have 4gb it is quite apparent why Blender would hang.

Anyway... No bug here, while freestyle can be improved in the future this is more of a general known todo and does not need a task.

Closing.

Hello, I am not very much agree with your assessment, the attached file is only 281KB with some modifiers, and in my case locks the PC, while this sub is a rendering in Freestyle that runs in just over three minutes, and it is more 103MiB

OK, I understand well the difference between ram and size, and I understand also that a very small file may generate abnormal memory consumption, but believe me when I tell you that this is an inherent problem with modifiers, and covers even groups and instances, said this today I'll do some tests on a different PC with less RAM,
This is a long period of time I use freestyle to generate 2D views and I use it daily, and I found other problems caused by other problems of various kinds.

Hello again, I did some tests and verified that the problem of the total drainage of resources and the block of my PC with 4 GB of RAM, occurs only when the active modifier bevel in horizontal bars, none of the other modifiers I take issue, I think the problem is very unusual, as well as being definitely caused by a failure of NPR engine optimization.

The issue here is not the bevel modifier but just exponential growth. ((You have the horizontal edges (8 * 6 * 16) * subdivisions + other geometry 10 ) = 7680 This number is reported in Blender. You then factor in the modifiers: 7680 * (2 solidify) * (7.3 bevel) * (23.3 subsurf) = 1,794,048 worth of edges for that object (way more than you need, try decrease the subsurf to see if it works) Anyway, no bug here.
