I have a problem with my webserver having slow downs in file transfers occasionally (when someone tries to download a .exe or .pdf by clicking a link). When this happens the download speeds will go from 230kbps to 30kps then to 0. The file size can vary from 30MB to 1MB, it doesn't matter. I can't find anything substantial in the apache logs. To fix this, I can map a drive to the server, copy the file to my desktop, and download speeds continue as normal. The server doesn't really get too much traffic so it's not likely that it's being overwhelmed. I don't know if this matters, but this server is a virtual machine. Here are the specs, it is a SuSE Linux 11 server running apache 2.2.10 with 1.5GB memory.
