Summary:                    [patch] Huge memory leak because memory of channel
cdr struct is never returned
Description: 
After two days of stress testing by making lots of calls across sip and
dahdi channels the asterisk process memory reached dizzy values: VSZ=3,2GB,
RSS=1,6GB before asterisk stucked completely (even the RAM of our server
(2GB) is finite ;-) ).

Actually this problem is not a question of load, but appears for each
single call.

Using valgrind the reason for that was quickly found: The memory of the
channel cdr struct (chan->cdr) is never returned, not for sip, not for
dahdi channels, when a channel is cleared.

Reproduce:
a.f.a.p. default configuration (modules.conf, etc.)
Make lots of calls and see ps's VSZ and RSS values.

Interested in a patch ? Or is someone revise this anyway?

I reopened the bug by request of Daniel who posted the following on the
asterisk developers mailing list:

I tested today 1.4.22-rc3, as I see it includes patch for issue
http://bugs.digium.com/view.php?id=13409.

This patch is causing me CDR problems, I use cdr_mysql (from addons 
package) as backend, and in a normal call A->B, this patch causes to 
post the CDR twice, giving me a constraint key violation (uniqueid is 
primary key in cdr table).

Can you reopen this? I've a slighty modified patch that calls also 
ast_cdr_detach but doesn't post a new cdr. I cannot post it or write a 
note to this issue because it is in 'fixed' state.

thanks
bye
