Usually you can also see the last test report of \"inprogress\" instead of \"ok\" or \"fail\".\n\nFurther, you can see the OOM from the kernel in syslog, and nail the victim to one of the python test workers, which shows about 1.5g of usage.\n\nThe easiest way to reproduce it locally is to run tempest like \u0027/usr/bin/time -v tox -eall -- MultiStore\u0027 and look at the max resident size in the result. You should see it be ~1.5g with this test, about 65m without it, and the same after applying this patch.","accounts_in_message":[],"_revision_number":1},{"id":"bc47d9a97a28fcd1edc6e28f653126b237207092","author":{"_account_id":4393,"name":"Dan Smith","email":"dms@danplanet.com","username":"danms"},"date":"2021-01-14 22:54:18.000000000","message":"Patch Set 1:\n\nBTW, here\u0027s the logstash I used this morning:\n\nhttp://logstash.openstack.org/#dashboard/file/logstash.json?query\u003dmessage%3A%5C%22tempest.api.image.v2.test_images.MultiStoresImportImagesTest.test_glance_direct_import_image_to_all_stores.*inprogress%5C%22\n\nand here\u0027s a failing test example:\n\nhttps://zuul.opendev.org/t/openstack/build/781590c5a8724e6d941bc6b6545794fa\n\nCheck the \"inprogress\" and \"Worker 2: N/A\" in there.","accounts_in_message":[],"_revision_number":1},{"id":"fc963839c4b17c74bc084abc603c9850ee1dbd35","author":{"_account_id":4690,"name":"melanie witt","display_name":"melwitt","email":"melwittt@gmail.com","username":"melwitt"},"date":"2021-01-14 23:19:35.000000000","message":"Patch Set 1: Code-Review+1\n\nThank you for all those details, very interesting stuff.

test was causing the\ntest runner to balloon to ~1.5G, which generates spurious OOMs in\nthe gate, resulting in worker death and failure.\n\nThis test was generating 10M of data with data_utils.random_bytes(),\ninstead of the default of 1K, for no apparent reason. We are still\nnot sure why, but this results in the memory ballooning, potentially\nbecause of BytesIO, or request.put() mishandling.\n\nRegardless, this is unnecessary, and causing failures in the gate,\nso this patch switches it back to the default, which works fine.\n\nChange-Id: I9f1ea0114531a735bd38ad54da7ce15fb2bf7f7c\n","web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/tempest/commit/8dfefcebeed7ddeebb6c7374169c8664ce523778"}],"resolve_conflicts_web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/tempest/commit/8dfefcebeed7ddeebb6c7374169c8664ce523778"}]},"branch":"refs/heads/master"}},"requirements":[],"submit_records":[{"status":"CLOSED","labels":[{"label":"Verified","status":"OK","applied_by":{"_account_id":22348,"name":"Zuul","username":"zuul","tags":["SERVICE_USER"]}},{"label":"Code-Review","status":"OK","applied_by":{"_account_id":22873,"name":"Martin Kopec","email":"mkopec@redhat.com","username":"mkopec"}},{"label":"Workflow","status":"OK","applied_by":{"_account_id":22873,"name":"Martin Kopec","email":"mkopec@redhat.com","username":"mkopec"}},{"label":"Review-Priority","status":"MAY"}]}],"submit_requirements":[{"name":"Verified","status":"SATISFIED","is_legacy":true,"submittability_expression_result":{"expression":"label:Verified\u003dCustom-Rule","fulfilled":true,"status":"PASS","passing_atoms":["label:Verified\u003dCustom-Rule"],"failing_atoms":[],"atom_explanations":{}}},{"name":"Workflow","status":"SATISFIED","is_legacy":true,"submittability_expression_result":{"expression":"label:Workflow\u003dCustom-Rule","fulfilled":true,"status":"PASS","passing_atoms":["label:Workflow\u003dCustom-Rule"],"failing_atoms":[],"atom_explanations":{}}},{"name":"Code-Review","status":"SATISFIED","is_legacy":true,"submittability_expression_result":{"expression":"label:Code-Review\u003dCustom-Rule","fulfilled":true,"status":"PASS","passing_atoms":["label:Code-Review\u003dCustom-Rule"],"failing_atoms":[],"atom_explanations":{}}}]}
