I'm afraid my system is not set up to enable crash dumps. I must admit that i never cared about this, and unfortunately, the default install does not seem to enable it either. If i am wrong: where would i find the dump? Also, since this is our main server, i prefer going back to 4.9 which seems to be more solid than 5.2 :-(. I simply don't have time to do more experiments. Thank ayou for your help anyway.
