FATAL: PressureDependMultiYield::updateActiveSurface<>:error

[MIRomero]

Hi,
I am trying to run a 3D nonlinear time history analysis of a soil model.
I am using the PressureDependMultiyield model in Bbarbrick elements.
The model consists of 35046 nodes and 31668 elements.
I am using the option of introducing the modulus reduction curves manually.
The error I am getting is:

FATAL: PressureDependMultiYield::updateActiveSurface<>:error in surface motion.
A=1.99e-24 B=8.3049e-13 C=6.71e-15 <t1&&t1> =0.345917

I have looked in the source code, and founded the error, but I am not able to interpret the problem using the script.

Can you please let me know how can I interpret properly the error, to figure out which of my modulus reduction curves is giving me troubles?
If I run the code in only one column of elements, it runs properly.

Thank you in advance for your time.
