[jira] [Commented] (ZOOKEEPER-1826) zookeeper ganglia module fails to read the output of stat when too many clients are connected

I also opened https://github.com/apache/zookeeper/pull/7 in case that's the right workflow.

> The ganglia zookeeper module uses a single 2048 byte socket.recv to get the response from the 'stat' command.  When there are more than a few clients connected, the list of connected clients fills the buffer before the script gets to the actual metrics its trying to report.
