Well, I always say that if you going to make things a mess, do it a spectacular way. Today I kicked off a data import job that went bad, and in the process of canceling said job, I canceled myself, and the job went rogue, and became a zombie and ate ALL the system memory, bringing the server to a deathly crawl and throwing a dozen developers temporarily out of work for about an hour, before I was finally able to kill the zombie, and balance was restored to the Universe.
