Im wondering if anyone else has seen the "Command terminated with signal 11 (core file generated)" message in the screen session running the miner software. I am on Ubuntu 20.04 with an older kernel 5.4.0-58-generic (needed for issues related to GPU mining).
Yep, that's the miner binary crashing for some reason. Impossible to know though because it's not open source so we cant run a debug version. Wrapping it in the shell script will reload it when it crashes so that segmentation fault would happen, but the application would restart right away.
