Firefox killed by sigbus while running inside Docker

Question

Firefox killed by SIGBUS kernel alert in Redhat Linux. Or once you start looking into Firefox logs you find out "A content process crashed Firefox" followed by connection errors seen in firefox.log.

Answer 1

Firefox crashes is probably because the memory limit for /dev/shm inside the container is too small Increasing this memory will solve the crash due to SIGBUS.

Add --shm-size "1g" while starting a docker container.

In docker-compose

services:
  yourservice:
    build:
      context: ./docker
    shm_size: '1gb'
