Comments:	By: Tilghman Lesher (tilghman) 2008-07-30 18:12:56 Let's try something along these lines.  Does this make the errors go away? By: Paul Belanger (pabelanger) 2008-07-30 18:33:42 Corydon76: Applied your patch, it seems to lock on 'module unload chan_iax2.so' now.  See attached files. By: Tilghman Lesher (tilghman) 2008-10-20 12:13:01 Tweaked patch slightly, so that it no longer blocks cancellation during socket_process(). By: Paul Belanger (pabelanger) 2008-11-04 12:22:27.000-0600 I should note, running the latest 1.6.0 branch, I was not able to reproduce this issue.  I can still test the patch if you like. --- $ svn info Path: .
