Non-convergence of piles SACS Pushover

When running an offshore platform pushover analysis I get a consistent error (ERROR-MAX. ITERATIONS EXCEEDED AT PILE JOINT "XX".

I ran the model using pinned connection at the base of the structure and it runs fine, so the error has to do with the soil and the pile. I also changed the displacement convergence requirement, but it does not help much. It seems that the pile has buckled.

I have it set up to continue analysis even if maximum iteration number is exceeded, but I just wanted to confirm this is acceptable. Is this just a regular way to let you know the soil is failing or the pile buckled?

Any input on this matter will be appreciated.
