ezstream not terminating

I'm running ezstream via lame, as so:

/usr/bin/lame -r -x -s 8 -m mono --preset cbr 64 - - 2> /dev/null | /usr/local/bin/ezstream -qvc configfile.xml

When the stream finishes, lame correctly exists but the ezstream process stays in memory (confirmed by a simple "ps ax"). The only way to remove it is by killing the process itself.

I'm not sure if this is an ezstream issue or not - feel free to flame me if it isn't ;)

Thx
