[Freeswitch-users] Already hung channels in 'show channels' output never go away

[Dmitry Sytchev]

Hi All
I'm using Perl ESL outbound script to bridge incoming call to sip endpoint.
I'm doing execute("bridge","sofia/user/somebody"), then processing events
like CHANNEL_HANGUP and EXECUTE_COMPLETE to determine bridge result.
Everything works fine, but original incoming call channel is never removed
from list:
After few calls I see original incoming channels in 'show channels' output:

7ae28028-4bc2-11e0-a92f-452f3d3d66ea,inbound,2011-03-11
12:32:27,1299835947,sofia/external/xxxx at 85.x.x.199
,CS_REPORTING,622xxxx,622xxxx,85.114.x.x,622xxxx,hangup,USER_BUSY,XML,route_in,,,,,,,,

,CS_REPORTING,622xxxx,622xxxx,85.114.x.x,622xxxx,hangup,USER_BUSY,XML,route_in,,,,,,,,
xxx.xxx.ru,,,HANGUP,,,

Also, when I try to stop freeswitch i see these messages on console:

2011-03-11 15:28:22.517063 [CRIT] sofia.c:1632 Waiting for 13 session(s)

2011-03-11 15:28:26.517065 [CRIT] sofia.c:1632 Waiting for 13 session(s)

Why these channels are not removed from list? I also noticed that memory
consumption by freeswitch process constantly grows call by call.
