I think you are missing the point - the problem is almost certainly NOT an OOM condition as there's nothing in the logs. It's a bug in the X server. The question is, how does one debug that. Here is the original question again: "I have a python application that kills X. I.e. the X process terminates,and all X programs receive broken links to the display and therefore also exit. The problem is, this python application is not supposed to kill anything, so I think it is a bug in X, but I cannot find any way to trace the fault. Even gdb says the application was killed, so exited normally, and results in no back trace. Is there any way in Linux to find out who did the "killing" ?" Lee
