After a lot of code digging and multithreaded debugging on the command line in GDB I have isolated and fixed the bug with the failing test on a 4 core machine. The test is also passing on a machine with many more cores. The issue is with backpressure buildup in the three problematic tests. The bolt threads are killed and the spouts are allowed to build backpressure to set up the scenario for the "event" in the test. I have tweaked the high/low watermarks for the backpressure as well as tweaked the spout counts to get the tests to work faster. There are some weird `PEX` errors that are coming up but if the CI runtime passes the 100-105min mark we can safely assume the `stmgr_unittest` is now passing in entirety in the CI pipeline as well. -- This is an automated message from the Apache Git Service.
