The stress utility is intended for catching of episodic failures. It runs a given process in parallel in a loop and collects any failures. Usage: $ stress ./fmt.test -test.run=TestSometing -test.cpu=10 You can also specify a number of parallel processes with -p flag; instruct the utility to not kill hanged processes for gdb attach; or specify the failure output you are looking for (if you want to ignore some other episodic failures). Do you find it useful? I use it for several years for all kinds of episodic failures (not just Go btw).
