Empire daemon stops forwarding output of emp run

[16m]

Hello,

I tried using remind101/empire:bfb5dafa5018ff8aae447154358a5ab2738d4103 and when running emp run, it looks like the empire daemon stops forwarding the container output after few seconds.

I ran a shell and quickly executed commands cmd1 to cmd9 (to make debugging easier):

$ emp run -a busybox sh

My shell stopped outputting right after the c of cmd6, but I kept typing and running the commands, and I could see the empire daemon was still up and showing the commands in its log (I omitted some parts of the output to make it shorter):

I tried several times with different images/shells and the behaviour is consistent. This doesn't happen with remind101/empire:0.12.0.

Thanks for reading!
