Urgh, reminds me of a production error that was caused by a job running on a timer, assuming that some other job would have finished by then. That lead to two obvious questions: - Why is it on a timer, instead of being triggered when the first job was done? - Why was that first job taking over an hour to process XML data? Turns out the second one was accidentally-quadratic, since it was parsing a whole document to process its first record; then re-parsing the whole document to process its second record; etc. and this made it very slow when the XML was reaching several hundred MB. Unfortunately, the solution we went with was to set the timer to run 20 minutes later...
