Overnight, I ran this test case on both an Ubuntu 16.04 ppc64le system and a RHEL 7.1 ppc64le system.
The test ran 219 times on Ubuntu, with 15 cores, for a failure rate of around 5%. Most of the time corruption was detected in the Canary ctor (before doing other work), but a few times in the dtor: $ grep "10000[12]" resmoke.log [js_test:fsm_all_sharded_replication] 2016-11-09T21:06:42.140+0000 s40019| 2016-11-09T21:06:42.140+0000 I - [conn59] Fatal Assertion 100002 at src/mongo/bson/util/bson_extract.cpp 50 [js_test:fsm_all_sharded_replication] 2016-11-09T23:11:56.413+0000 s40019| 2016-11-09T23:11:56.412+0000 I - [conn1] Fatal Assertion 100001 at src/mongo/bson/util/bson_extract.cpp 46 [js_test:fsm_all_sharded_replication] 2016-11-10T03:49:43.577+0000 s40019| 2016-11-10T03:49:43.576+0000 I - [conn47] Fatal Assertion 100001 at src/mongo/bson/util/bson_extract.cpp 46 [js_test:fsm_all_sharded_replication] 2016-11-10T04:54:20.748+0000 s40019| 2016-11-10T04:54:20.745+0000 I - [conn28] Fatal Assertion 100001 at src/mongo/bson/util/bson_extract.cpp 46 [js_test:fsm_all_sharded_replication] 2016-11-10T04:56:43.929+0000 s40020| 2016-11-10T04:56:43.929+0000 I - [conn30] Fatal Assertion 100001 at src/mongo/bson/util/bson_extract.cpp 46 [js_test:fsm_all_sharded_replication] 2016-11-10T07:26:14.013+0000 s40019| 2016-11-10T07:26:14.013+0000 I - [conn3] Fatal Assertion 100001 at src/mongo/bson/util/bson_extract.cpp 46 [js_test:fsm_all_sharded_replication] 2016-11-10T07:52:45.732+0000 s40019| 2016-11-10T07:52:45.698+0000 I - [conn1] Fatal Assertion 100002 at src/mongo/bson/util/bson_extract.cpp 50 [js_test:fsm_all_sharded_replication] 2016-11-10T07:54:45.606+0000 s40020| 2016-11-10T07:54:45.606+0000 I - [conn30] Fatal Assertion 100001 at src/mongo/bson/util/bson_extract.cpp 46 [js_test:fsm_all_sharded_replication] 2016-11-10T08:28:04.278+0000 s40020| 2016-11-10T08:28:04.277+0000 I - [conn13] Fatal Assertion 100001 at src/mongo/bson/util/bson_extract.cpp 46 [js_test:fsm_all_sharded_replication] 2016-11-10T09:28:24.221+0000 s40020| 2016-11-10T09:28:24.221+0000 I - [conn32] Fatal Assertion 100001 at src/mongo/bson/util/bson_extract.cpp 46 [js_test:fsm_all_sharded_replication] 2016-11-10T09:41:14.880+0000 s40019| 2016-11-10T09:41:14.800+0000 I - [conn48] Fatal Assertion 100001 at src/mongo/bson/util/bson_extract.cpp 46 [js_test:fsm_all_sharded_replication] 2016-11-10T10:35:58.143+0000 s40019| 2016-11-10T10:35:58.118+0000 I - [conn2] Fatal Assertion 100001 at src/mongo/bson/util/bson_extract.cpp 46 [js_test:fsm_all_sharded_replication] 2016-11-10T11:06:01.027+0000 s40019| 2016-11-10T11:06:01.027+0000 I - [conn1] Fatal Assertion 100001 at src/mongo/bson/util/bson_extract.cpp 46 [js_test:fsm_all_sharded_replication] 2016-11-10T12:37:43.100+0000 s40019| 2016-11-10T12:37:43.100+0000 I - [conn1] Fatal Assertion 100001 at src/mongo/bson/util/bson_extract.cpp 46 [js_test:fsm_all_sharded_replication] 2016-11-10T13:31:31.912+0000 s40020| 2016-11-10T13:31:31.912+0000 I - [conn1] Fatal Assertion 100001 at src/mongo/bson/util/bson_extract.cpp 46 The test ran 227 times on RHEL without issue.
