mumps allocation warning

The mumps allocation factor keeps increasing while the simulation is running, and it's up to a value of 10.

I was wondering if I should let if finish, if it does, or change the Pivot threshold to 0.01 as is suggested here: https://www.comsol.com/support/knowledgebase/1134

However, I do not fully understand how that affects the solver.

Others have suggested that it could be due to the boundary conditions, which is not something I can change as I am trying to reproduce a comsol-model already published in an article.

Would be helpful to get some guidance regarding this issue!
