Hello Pedro,
Sorry for the late reply, I have somehow missed your question.
I opened SR on 18.09.2018 and since then there was not much progress with it. I have provided core dump to TAC but they said they cannot find anything interesting in it and asked for remote session few days ago. So far, nobody contacted me yet about it. In the mean time, situation is still the same and some times it is getting real bad. I mean just look at this:

Just prior the crash the system load average will go real high, 3.00 - 5.00 or so. I wonder what is difference between those 3 appliances (where you do not have such issue) and the other 7....
