PRB: Render Farm Jobs Terminate Prematurely

= SYMPTOMS =

Lack of swap when you really have enough swap set results in renders prematurely terminating.

= CAUSE =

When render farm jobs are run with soft -R, and you use pre- and post-frame render scripts, SOFTIMAGE 3D (SI3D) uses the system call to execute the render scripts; this causes the problem. When the render type is set to mental ray, enough memory and swap is required to accommodate multiple copies of the scene: mental ray’s internal version, SI3D’s version, and a duplicate version that is created when the pre- and post-frame scripts are run.

For many SI3D scenes, this is a problem; with at least 192 MB in your machine, with 500 MB of swap, this is still insufficient.

= RESOLUTION =

If virtual swap space (swap -a -v) is properly set, problems will not occur because the computer is tricked into thinking the memory is there, but the memory is never accessed.

= STATUS =

This behavior is by design.
