Only with 2 network outputs. One network output works without errors.

Native encoder?
Is a specific input file needed to reproduce or does it also crash with

It also crashes with testsrc

Here is strace with testsrc in input and 2 rtmp outputs.
I'll provide any other information if you will point me how to gather it.
