This on Limewire 2.5.5 Linux.

Click download. Download goes to 100% w/o a hitch. At 100% tells me file is corrupted. I tell it to download anyway. File vanishes, does not appear in download directory or incomplete.

Occurs on roughly one in three downloads. Repeating thusly failed download from same host, same file can result in success, or failure, again about one in three.
