looks like you have a network level issue - the latency is too big. Try run tracert www.your-server-name.com
to see where the biggest part it.

  No lost packets but quite a variation in ping time ¨C minimum 604mS, average 759mS (IĄ¯d
say mean around 630mS) but maximum of 3429mS [about every 10th ping was over 1200mS]

  do a quick test to see if you get any packet loss:

  ping -t www.your-server-name.com

    Just checked and in my httpd.conf file there is an item ĄŽtimeoutĄ¯ with a value of 120
.. changed it to 300 + restart .. no change so set it back to 120

    For apache 2.2.x, it is in conf/extra/httpd-default.conf  from the httpd root folder.
but since you dont known about it it is probably still the default 300 seconds. Setting it
too small will break(reset) http connections when idle time of downloading is too long, more
likely to hapeen over unreliable and slow links.

      what is the Timeout value in your configuration?

        It seems to me that the problem might be with the network connection, not with the
Apache server configuration. Image and Flash files are usually larger than web pages: perhaps
there's some limit or timeout that's being reached? Of course, this doesn't account for css
files, so there's an exception. How about when you right- or ctrl-click on the image and say
to download it? Does that work? Can you check with the providers of your satellite link about
this problem?

         

        Regards,

        Hi all

        I have a Virtual Server (from 1&1) running Apache 2.2

        When any of my sites is accessed by?a 'hard line' connection (ie ADSL) they
        work fine. However where I live in rural Spain my connection is by
        bi-directional Satelliet link (100Mbps max) .. whenever a site is accessed
        over the sat-link I get a lot of incomplete graphics files (only top half of
        image or so), frequent failure of CSS files to load and no Flash files at
        all! Yet the same file accessed by ADSL is fine.

        Followed Apache.org advice and have included "EnableSendFile Off" and
        "EnableMMAP Off" in the config file ("Win32DisableAcceptEx" rejected by
        restart so not in) .. rebooted and no difference.

        Any suggestions/pointers etc

        Graham
