Description Robert Munteanu CLA 2011-01-11 07:06:47 EST 
Build Identifier: 

I have seen on some occasions that Eclipse 'hangs' during network operations. Trying to restart Eclipse has no effect , as the network-related jobs are all hung.

By taking a thread dump I have noticed that:

- one thread holds the lock for org.eclipse.core.net.ProxyProvider ;
- other threads are waiting to lock the ProxyProvider;
- the thread holding the said lock is waiting for a process to exit

Running ps I have noticed that Eclipse has a child process spawned: /usr/lib/libproxy/pxgconf , which is by itself hung.

Reproducible: Sometimes

Steps to Reproduce:
1.Perform network operations in Eclipse

Even though the faut is clearly in an external component and not Eclipse, I think a guard should be but in place for such misbehaviour on pxgconf's behalf.

It's actually running '/bin/sh -c 'env'' and your env process has become defunct...

This should all be fixed by bug 332728 where we'll use Java API for this by default.
