[Asterisk-Users] Asterisk 1.0.9-BRIstuffed-0.2.0-RC8o memory leak when using call files ?

[Bruno.Voigt at ic3s.de]

Hi all,

I'm using Asterisk 1.0.9-BRIstuffed-0.2.0-RC8o on box A with a TE410P 
(EuroISDN cpe)
connected to another similar asterisk box B acting as EuroISDN master.

I'm performing some load tests by contiously feeding up to concurrent 30 
call files to /var/spool/asterisk/outgoing/ on box A
which inititate via a dialplan context/extension a outbound call 
(redirected via chan_local) to box b
playing some preexisting wavfiles followed by hangup.

I see a memory growth for the asterisk process from 39M VIRT / 11M RES to 
179M VIRT / 22M RES after 1000 completed calls.

The box B acepting/recording the calls doesnt show such a memory growth 
over time.

Are there known issues about call files / memory growth in asterisk 1.0.9?

The dial construct via chan_local is there to have some additional 
information about the callfile
to be tunneld thru asterisk and to provide direct feedback about the call 
success/failure to the callfile generator process.

TIA for any hints,
Bruno
