Memory error while using shared arrays

My reading of the code is that is shoudl print what the limits are.
I think you may have hit a bug!
Ah though - you are using version 0.7 We are told 0.7 and 1.0 should be equivalent.
Could you try version 1.0.3 maybe?

On a Debian 9 system with 64 gigs of RAM:

sysctl -a | grep shm

kernel.shm_rmid_forced = 0
kernel.shmall = 4294967296
kernel.shmmax = 68719476736
kernel.shmmni = 4096

Could you run this sysctl comand on your system please?

From 1.0.3 stdlib/SharedArrays.jl

  shmmax_MB = div(parse(Int, split(read(`sysctl $(pfx).shmmax`, String))[end]), 1024*1024)
    page_size = parse(Int, split(read(`getconf PAGE_SIZE`, String))[end])
    shmall_MB = div(parse(Int, split(read(`sysctl $(pfx).shmall`, String))[end]) * page_size, 1024*1024)

    println("System max size of single shmem segment(MB) : ", shmmax_MB,
        "\nSystem max size of all shmem segments(MB) : ", shmall_MB,
        "\nRequested size(MB) : ", div(slen, 1024*1024),
        "\nPlease ensure requested size is within system limits.",
        "\nIf not, increase system limits and try again."
