Has anyone ever had CSIBridge or SAP2000 crash during an analysis and get either of the following messages?

I am analyzing prestress i-girder bridges under 48 different ground motions using nonlinear modal time history. I have tried using both area object model and spine model. Also I lowered max mesh size which seemed to help sometimes. Also, using the standard solver it tells me I get numerical errors, decreasing mesh size reduces numerical errors. I think my computer is getting overloaded but I dont know how to verify this, I have tried another computer with slightly higher performance specs but to no avail. The reason I think this is that the failed cases are the ones with the longest ground motions durations. Overall I have found no trend and there seems to be no consistancy between bridges which cases fail.
If anyone has had these error messages, how did you resolve them? I have contacted CSI but no response yet.
