    Corrupt Downloads

    Hi,

    We moved to a dedicated server from a reseller account. We have a store that has all downloadable products. While using my reseller account we never had one complaint concerning a corrupt file. Once we moved to a dedicated server we had complaints almost every day.

    What could be causing people to be getting files that appear to be corrupt but they are not .

    They have seven download attempts given and if they try at different times eventually they get a good file. So the files are not corrupt but for some reason they are getting bad files sometimes.

    Any ideas and solutions would be greatly appreciated.

    Thanks

    Rick

    Check with those whose who got the 'corrupted' files, are they terminated prematurely, ie contains less bytes than the original files ?

    How are you allowing them to download ? via ftp or via http ?

    Some have been terminated prematurely, some when downloaded contain less bytes than they should.

    They are all downloaded via http

    I noticed that you are using Linux and that is something which I am not familiar with but probably some kind of setting in Apache should do the trick. Hope that someone could give you something more constructive.

    By the way how big are the files on average ?

    Make sure your "TimeOut" in the httpd.conf is not to low, if the file is large and it takes longer to download then you have set your timeout this will cause the download to be corrupt. This is a problem i have encountered before, this would cause downloads to be fine sometimes and others that are larger/take longer to be corrupt.

    There really is no clear reason why there would be any download corruption. Are you using any special type of script to let them download the software?

    The "timeout" was very low so I made it 300.

    That is most likely the problem, let me know how it goes.
