asterisk users - Jun 2010 - Endless loop with asterisk directory

Every so often, I have an asterisk 1.4.22-4 system that goes into an endless
loop with the following:

[Jun 1 13:30:44] VERBOSE[13160] logger.c: -- Playing 'dir-nomatch'
(escape_digits=) (sample_offset 0)
[Jun 1 13:30:44] WARNING[13160] file.c: Failed to write frame
[Jun 1 13:30:44] WARNING[13160] file.c: Failed to write frame
[Jun 1 13:30:44] VERBOSE[13160] logger.c: -- Playing 'dir-intro'
(language 'en')
[Jun 1 13:30:45] VERBOSE[13160] logger.c: -- Playing 'dir-nomatch'
(escape_digits=) (sample_offset 0)
[Jun 1 13:30:45] WARNING[13160] file.c: Failed to write frame
[Jun 1 13:30:45] WARNING[13160] file.c: Failed to write frame
[Jun 1 13:30:45] VERBOSE[13160] logger.c: -- Playing 'dir-intro'
(language 'en')
[Jun 1 13:30:45] VERBOSE[13160] logger.c: -- Playing 'dir-nomatch'
(escape_digits=) (sample_offset 0)
[Jun 1 13:30:45] WARNING[13160] file.c: Failed to write frame
[Jun 1 13:30:45] WARNING[13160] file.c: Failed to write frame

Etc...

This happens until the file system fills up with a huge asterisk/full log, and
then asterisk crashes.

A lot more detail on the issue is here:
http://www.freepbx.org/forum/freepbx/users/asterisk-directory-looping

The FreePBX project-lead has said that this is clearly an asterisk issue, and
has nothing to do with them
(http://www.freepbx.org/forum/freepbx/beta-program-issues/loop-when-the-call-is-not-answered-by-the-extension#comment-27032).

Anyone here seen this before? Any ideas as to how I can get this issue resolved,
short of just entirely disabling the app_directory.so ?

Other people seeming to have the same problem here
(http://www.trixbox.org/forums/trixbox-forums/help/trixbox-2-6-0-7-directory-not-working-looping),
but none of the suggested solutions from either thread has worked for me.
