Please tell me what these dForce Log Errors mean

I applied a dForce Modifier and ran the simulation.  It concluded as expected to my mind, but there was an error flagged by Daz Studio.

It just a collision of a t-shirt against a ground plane.  It worked as far as I am concerned, so why does Daz Studio flagg an error ?

Ignore the orderly shutdown bits - they are not dForce.

The springs are the edge lengths of the dForce model, having them shorter than the Dynamic Offset can cause issues as the simulation has to stretch the edge to match the offset and then wants to pull it back to the rest length, which can slow the process and even lead to explosions. The clfinish(-36) does look like an actual error, but I'm not sur what it means

Looks to me like an error reported from the OpenCL lib propogated out. In laymen's terms the software dForce is based on reported an error and the dForce software ignored it so it got to the logging system and got recorded. 

Since the simulation completed and the result looks right don't worry about it. I see logs full of this sort of stuff all the time in my day job. A lot of times errors get reported that don't prevent the software from working.

Generally if it says WARNING rather than ERROR it's not going to be fatal (at leastb as far as the application is concerned, it may stop you from getting the desired result).
