Summary:                    ERROR[5003]: channel.c:2043 __ast_read: ast_read()
called with no recorded file descriptor.
Description: 
Performed an upgrade from 1.4.22 to 1.4.24 running on CentOs 4.  Used the
same "slim" configuration that I used in 1.4.22, which worked fine.

Calls are processing, but connecting to the console gets the following:

[Mar 23 13:08:05] ERROR[5003]: channel.c:2043 __ast_read: ast_read()
called with no recorded file descriptor.
[Mar 23 13:08:05] ERROR[5003]: channel.c:2043 __ast_read: ast_read()
called with no recorded file descriptor.

This repeats continuously.  If I issue a show channels, I get some output
and it seems to stop the ERROR messages, though it seems the "show
channels" does not complete.  You can get the CLI command and * will still
be trying to spit out a few channels below it.

The system load is also very high (2.38 with 50 or so concurrent calls),
though CPU usage is low... it must be coming from somewhere else. 
Typically this load under 1.4.22 would show perhaps a 0.2 or 0.3 load.

I am seeing similar notices in two of my open bug reports.
I also have a looping problem which effects my sites differently. The loop
appears in different places ie. IVR, ACD, wake up call.

I have valgrind posted on http://bugs.digium.com/view.php?id=14918
We have revert r165796 on 1.4.24.1 in order to have working AGI and IVR
audio on bug report http://bugs.digium.com/view.php?id=14843

IMHO there must be some relation between these three tickets and possibly
all are related to r165796 or that revisions' root cause.
Perrhaps the root cause is the high CPU load caused by what is seen in
14723...
