93137 Mp3 Player Not Playing MP3

I have a flash mp3 player script that has a backend admin area written in php. The script automatically writes the playlist to xml as soon as a song is uploaded or the refresh playlist button is pressed. Also the admin area can create clips for the player and cuts the mp3s. It seems on one particular linux server the songs load in the player but will not play. If a clip is loaded though it will play. After uploading full songs the and then looking in the xml playlist, this file doesn't get fully written. The code is cut off. Need help to fix this. I think this must be something simple since it does work great on many other servers. I'll send demo links of the player and code if needed through the PMB. Thanks
