1) large stress differences between integration points within an element (high stress gradient). I recall being confronted with this problem even though my Python scripts usually pick specifically the results for a specific component of the stress tensor at a precisely defined integration point (and not any average value over the element or a non-specific value like Mises stress or the like).
2) possibly also if you have your data written to files using a Python script and loop over several output databases. I had to observe that Abaqus tends to screw up data between different simulations (i.e., provides the data from the first simulation also for the ones to be evaluated subsequently).
