ok, the -j 4 is the problem running "make -j 4 install-bin install-traceevent-plugins" BUILD: Doing 'make -j4' parallel build BUILD: Doing 'make -j4' parallel build will run paralel make instances for install-bin and install-traceevent-plugins which will eventually touch same files and crash.. the main perf Makefile is actualy detecting number of cpus and runs Makefile.perf with -j X option so there's no need to specify it on top level.. you can always customize it via JOBS=X make variable so if you don't specify the -j X option it will run the 'Makefile.perf install-bin install-traceevent-plugins' with -j X set and it should execute sequentialy and fix your problem thanks, jirka
