SAMG error code 211

Hello,
The simulation of my flow model, transient, free and movable stoped with a new window error saying: "SAMG terminated with error code 211!".
Do you know what does that error means? thanks!

According to this doc:

http://feflow.info/fileadmin/FEFLOW/download/other_docs/samg_user22c-11.pdf

Error in performing the setup optimization AMG solution phase
200 General error (unclassified)
210 Divergence of the method
220 Error in relaxation (smoothing)
230 Error in ILU (smoothing)
240 Error in ILUT (smoothing)
250 Error in inter-grid transfers
260 Error in alternating ìSchwarz processî

There is no error or warning 211... This document might be outdated and I can't find a more recent one, but I hope this helps.
