I've no idea what the error codes mean, but a colleague of mine was once faced with system error code 47 (I think) when using Huang's UMAT for crystal plasticity. Using a smaller maximum timestep solved the problem, as it seemed Abaqus was incorrectly estimating the timestep it needed and not reducing the timestep until the problem was already diverging. Worth a try maybe? For a given analysis, does it always crash in the same place?
This error just appeared in my analysis and the reason was a divison by zero caused by an un-initialized variable. Look for standard errors like mis-shaped arrays, wrong variable types because of implicit declaration, that kind of stuff. Normally, you will find a reasonable explanation for the esoteric error message.
