Description:When using mixmonitor application to record outgoing sip calls, i can barely see that in instant the memory usage was very high to the extent that the machine was extremely unstable. the calls generated on this server was about 5-20 minutes / call.

If this happen, asterisk still continue to function no core dump or error reported on the console. except choppy audio simply because there's no available memory left to use.

dialplan snippet:

[macro-DialSipGw]

exten => s,1,Mixmonitor(${CALLERID(num)-${ARG1}.wav|a)
exten => s,n,Dial(SIP/itsp/${prefix}${ARG1}|60)
exten => s,n,Hangup

[outgoing]

exten => _91XXXNXXXXXX,1,Macro(DialSipGw,${prefix}${EXTEN:1})

Wrong:

[outgoing]

exten => _91XXXNXXXXXX,1,Macro(DialSipGw,${prefix}${EXTEN:1})

Correction:

exten => _91XXXNXXXXXX,1,Macro(DialSipGw,${EXTEN:1})

I'm not sure how to debug this, but removing mixmonitor solve * stability problem.

exten => s,1,Mixmonitor(${CALLERID(num)-${ARG1}.wav|a) ?

Did you maybe mean to do

exten => s,1,Mixmonitor(${CALLERID(num)}-${ARG1}.wav|a) ?

qwell: yes heheh, i'm sorry i guess i need to sleep now :)

Can you please enable MALLOC_DEBUG in the 1.2 Makefile and then recompile. You should then have show memory * commands that will show you where memory is leaking (if it is).

file: alright will do that thanks, i will post results asap, as soon as i convince  the customer again to enable the voice recording. thanks
By: Ronald Chan (loloski) 2007-02-26 16:03:30.000-0600

file: please close this for the meantime since the customer, has an alternate route to record their conversation, if the problem resurface on my other implementation i'll ask to re-open this again.

Thanks

Ronald
