UtilLoadTest_0 fails due to SolverTest-related timeout #1916

Open adamfarley opened 4 years ago

adamfarley commented 4 years ago

Describe the bug The system test times out, with an instance of the SolverTest hogging each of the threads.

With tests chosen at random in that kind of load test, the tests that don't overrun are completed quickly, and replaced by another test from the bucket. So, eventually, all of the concurrent threads are held by one of the test types that does overrun, which is what's happened here.

To Reproduce Test_openjdk8_hs_extended.system_s390x_linux #256/UtilLoadTest_0
