[Freeswitch-users] Unexpected hangup of FIFO consumer

Hi, I found out that if fifo_music is set before "fifo out wait", the consumer would get hung up after 30 s. <action application="set" data="fifo_music=/usr/local/freeswitch/sounds/music/8000/suite-espanola-op-47-leyenda.wav"/> <action application="fifo" data="myfifo out wait" /> If I remove the line that sets fifo_music, consumer can stay in the channel forever. Does anyone know what may be causing this problem? Thanks, JB
