[Richard Mudgett (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-26297?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=231898#comment-231898 ] 

Richard Mudgett commented on ASTERISK-26297:
--------------------------------------------

It is a debugging tool to find a problem you are *currently* having and like a lot of debugging tools leaving it enabled for normal operation is going to kill your performance.  The only other way to debug locking problems is to attach gdb to the Asterisk process and get a backtrace.  It is just much harder to find deadlocks that way.

> After upgrading to 11.23 on el5. Extension to extension calls and external PSTN calls are badly distorted and signalling/call set up is delayed between 2-30 seconds.  The problem is also reproduced on x64 el5
> This was not an issue in 11.16 or 11.20 so I am marking this a regression.  
> I don't know where to start debugging this so I am attaching messages file with sip set debug on rtp set debug on verbose and debug logging options
> Timertest was clean
> res_timing_dahdi.so
