[asterisk-users] Asterisk crashing when recording ConfBridge calls (10.7.1)

[Markus]

Hi list,

since I enabled call recording in my ConfBridge bridge profile, after 
about every 5th held conference (sometimes after 3, sometimes after 10, 
it depends), when the last users exits the conference, Asterisk crashes. 
Is this a known error? I'm using Asterisk 10.7.1 on CentOS 64bit with 
the official RPMs.

And here's the snippet from confbridge.conf:

[chatfire-internal-bridge]
type=bridge
record_conference=yes
sound_has_joined=/var/lib/asterisk/sounds/chatfire_betritt_konferenz_6
sound_has_left=/var/lib/asterisk/sounds/chatfire_konferenz_verlassen_6
sound_only_person=/var/lib/asterisk/sounds/chatfire_erster_anrufer_6
sound_there_are=/var/lib/asterisk/sounds/chatfire_es_befinden_sich_derzeit_6
sound_other_in_party=/var/lib/asterisk/sounds/chatfire_anrufer_in_der_besprechung_6
sound_get_pin=/var/lib/asterisk/sounds/chatfire_intro_6

And the dialplan:

; internal conference only
exten => 06,1,Answer()
exten => 06,n,Set(CHANNEL(language)=chatfire)
exten => 06,n,Set(CONFBRIDGE(user,template)=chatfire-internal-user)
exten => 06,n,Set(CONFBRIDGE(bridge,template)=chatfire-internal-bridge)
exten => 
06,n,Set(CONFBRIDGE(bridge,record_file)=/tmp/chatfire-${STRFTIME(,,%C%y%m%d%H%M)}.wav)
exten => 06,n,ConfBridge(22*68*39*09,,,chatfire-internal-menu)
exten => 06,n,Hangup()


Help! :)

Thank you,
Markus
