Subject [jira] Updated: (HADOOP-7146) RPC server leaks file descriptors
Date Tue, 15 Feb 2011 21:20:58 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-7146?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Todd Lipcon updated HADOOP-7146:

    Attachment: fd-leak.txt

here's a fix, but should add a unit test. There's a way you can use platform mxbeans to find
the number of open FDs, but I can't quite track down the right API at the moment.

> Both the Listener and Responder thread call Selector.open but don't have a matching .close().
This causes a leak of anonymous pipes. Not a big deal because people rarely close and re-open
servers, but worth fixing.
