[jira] Resolved: (IO-93) FileSystemUtils needs to call
Process.destroy() on exec'd processes
[ http://issues.apache.org/jira/browse/IO-93?page=all ]
Stephen Colebourne resolved IO-93.
----------------------------------
Resolution: Fixed
Was more complicated than I expeted. I have coded a solution, however it really seems that Process in the JDK is basically rubbish. Anyway, I've improved what we have, rather than go to a full blown commons-exec solution.
I can't test or reproduce you're problem on my Windows box. Since you have a test case, can you please try the latest code and reply back (by closing or reopening the call) as to whether the problem is fixed. Thanks.

> Components: Utilities
> Affects Versions: 1.2

> Calling the FileSystemUtils.getFreeSpace() method multiple times (~3000) will generate an IOException with the following text: "Too many open files". Documentation from Sun says this problem is due to not destroying the java.lang.Process object returned from the System.exec() call.
> Some sample code I wrote confirms that calling destroy prevents this error from occurring.
