3,200% CPU Utilization

A while back my machine was so messed up that I could barely ssh onto it. 3,200% CPU utilization - all 32 cores on the host were fully utilized! Compare that to my last bug where it only used 1 core, 100% Fortunately, it was using Java 17 runtime which...

I wasn’t very familiar with the class so I started to look around, focusing on treeMap and unrelatedObjects to see if my assumption that they never exceed 1,000 holds. despite no red black tree, if I had run the experiment, I would expect to not to be able to reproduce for the same reason as ruby: the GIL.ElixirnoAlthough there are many third party implementations of the red black trees in Elixir (and Erlang), the programming model makes it impossible: data structures are immutable and interactions between threads are limited to message passing.From the table, the most interesting one is C++ because I was not expecting to be able to reproduce the problem due to my hypothesis from the last section. This NPE only occurs once per API handler worker thread before which was not enough to trigger our error rate alarms.
