-----------------------------------------

Hi Joshua
It seems like error was caused by 8. POST http://10.34.190.55:8088/ari/channels/externalMedia?app=ari-satan&external_host=172.23.34.19%3A16384&encapsulation=rtp&transport=udp&connection_type=client&format=slin&direction=both request
We changed format parameter from slin to ulaw and crashes disappeared
Maybe it would help somewhere somehow
