MQ Docker container exists with error: You cannot run more than one instance of this program

  • 1.  MQ Docker container exists with error: You cannot run more than one instance of this program

    Posted Thu July 21, 2022 10:25 AM
    Trying to run MQ in a Docker container exits with the error "You cannot run more than one instance of this program".
    There are no other containers running on the machine.

    I am running an AMD64 container on a Mac M1 through the emulation provided by Docker, but I don't think this error would be related to the use o emulation.

    Any ideas?

    Hi.  This is a known problem, and is related to using Apple silicon.  See this issue: Apple M1 or ARM64 support. I'm afraid there isn't a work around at the moment.

    Is there an ETA for when M1/M2 (ARM) support for MQ will be available? ARM macbooks have been available for quite some time and are given to engineers who then are unable to do any work due to this lack of support.
