Its hard to comment without more specifics as to what caused of the crash. Was this an application level exception being caught?
So you say if you recompiled with Su361 the same still occurred? (As opposed to using the earlier SU.)
Does this happen with a single call, or only underload? is there an additional data points that can be provided about what media activity is taking place on the system at that time?
We would need to see the actual stack output to pinpoint the libraries involved in this case. I know there were some changes made in the codebase for merging baselines between Linux and Windows releases, and things were seen and addressed.
Overall, issues like these would need to reported via proper channels to the Dialogic Support Group, but I can provide some guidance if can answer above questions.
