    serving large files through apache

    hi guys,

    I am serving large files through apache web server. But in sometime apache stops to respond so I have to restart the web server.

    I can understand that this is a memory related problem. Alternatively i changed to transfer method to ftp, there was no problem then but for some reason I have use http while serving the files.

    I tried to add ram (1GB) but this did not fix the problem.

    I know that apache gets the file into memory and then sends it to client. I read about sendfile thing but I could not connect it with apache...

    Any suggestions and experiences will be very much appreciated

    hmmm, have you thought of setting up a second webserver app on a different port to server the files - you could then use a program that is less heavy on usage and ram than apache

    just my .2c

    Sounds like you don't have enough apache server processes available.
    Bump up the "MaxClients" number, and/or check out mod_ioboost which will immediately free up apache to do other stuff rather than serve up the big files.

    not off the top of my head, but could you not setup anonymous ftp and link to the files that way ?

    mod_boost and MaxClients are values that can be adjusted in httpd.conf on your server.

    I would also suggest tweaking up your Apache before concidering other webservers, as I suspect you'll end up with more-less same problem.

    I am not 100% sure, but I think you can instruct Apache to send files, if not directly, but then to lower the memory buffer before sending files (like, load 1% of file in memory (which would be like 1 mb, if file is 100MB) and then send it, then load again 1% etc etc etc).

    Also take a look at: http ://httpd.apache.org/ docs-2.0/mod/core.html#enablesendfile

    (dunno, what files are 'static' nor what files are you offering for download).

    And just one suggestion, try (costs nothing to mail people @tucows, download.com etc to get you started in good direction (will certanly not offer you complete solution, but...)

    Cheers,
    Aleks

    mod_ioboost is not a standard module, its commercial in fact
    I'll dig up their info, the module is awesome.

    I would try changing the MaxClients. By default apache has a small value for MaxClients, I forget what it is though.
    But once you do this more people can connect at a time and since you are serving large files once one person is connected they are there for a long time.
