> We recently ran across a strange higgs-bugson that manifested itself in a critical system that stores and distributes the firm’s trading activity data, called Gord. (A [[https://en.wikipedia.org/wiki/Heisenbug#Related_terms | higgs-bugson]] is a bug that is reported in practice but difficult to reproduce, named for the [[https://en.wikipedia.org/wiki/Search_for_the_Higgs_boson | Higgs boson]], a particle which was theorized in the 1960s but only found in 2013.) In this post I’ll walk you through the process I took to debug it. I tried to write down relevant details as they came up, so see if you can guess what the bug is while reading along.
