uploading MP3

When uploading MP3 or MP4 files, after approximately 60 seconds I get the connection has been lost.

I have changed the config/jee-container.xml

<property name="connectorProperties"> <map> <entry key="maxPostSize" value="100000000"/> </map> </property> to '<bean name="httpConnector" .........>'

after this happens, I have the option to reload, which creates a new user in the room.  The fill does not show up in the uploaded folder.  I have to restart red5-ubdeb2 restart  to get rid of the ghosted users and additionally, sometimes the file I was trying to upload will also show after the restart.  I have hundreds of files to upload and I would really like to make this work smoothly has I have other users waiting to use openmeetings.
