I first noticed it when running `./run_tests --with-coverage` which would run nosetests in the Allura dir and would not use --processes=N because of the with-coverage param. So basically just a regular run of the tests in the Allura dir would cause the CPU to go into 100% usage and the tests wouldn't finish. Couldn't ctrl-C or profile them, had to kill -9 it. That was on Centos 5.10 and a workaround was to run with --processes=N and then the tests would finish fine. On the Ubuntu vagrant image, I didn't encounter any problem in the first place. So perhaps related to the environment. I tried to narrow down to a specific test that might be the culprit. I found tests consistently got up to TestSecurity.test_auth (which is a bit weird and old test anyway). And also that commenting out that test let them all pass. But I'm pretty sure Alex said he dug into this as well and found variation in what tests could cause the problem. I think he told me that going back in git-history before the problem, and then adding a single test (a copy of an existing one) caused the problem. So perhaps some limit, or resource tipping point is hit. Alex or Igor, any more data points you know from what you've seen? Anyone else seen anything like this? Or have ideas for how to approach nailing it down better? -- Dave Brondsema : [email protected] http://www.brondsema.net : personal http://www.splike.com : programming <><
