Created attachment 547 [details] reduceSimultaneousDownloads.patch Recently, Microsoft has started blasting multiple (threaded?) requests for different sections of the same, huge, windowsupdates file. This can easily result in the same url being downloaded by multiple wget commands. I have seen 4 or 5 identical downloads starting within 1 second. This results in a corrupt file, that is identifiable as the file grows to a larger than 100% size since multiple wgets are dumping data onto the same file. (We have a slow internet connection, so between the time when the "lock" file is deleted and wget actually started downloading data allowed multiple threads to start. A ps ax | grep <url> shows multiple wget and download commands running.) I have attached the modifications I have made to reduce the problem. I'll know better how effective it is after the next patch Tuesday. Perhaps a better programmer could figure out how to effectively use flock in this situation to make it fool-proof...
