  • User limits for processes or files have either been exhausted, or recommended limits for user configuration have not been set.

    shell> ulimit -a
    core file size (blocks, -c) 0
    data seg size (kbytes, -d) unlimited
    file size (blocks, -f) unlimited
    max locked memory (kbytes, -l) unlimited
    max memory size (kbytes, -m) unlimited
    open files (-n) 256
    pipe size (512 bytes, -p) 1
    stack size (kbytes, -s) 8192
    cpu time (seconds, -t) unlimited
    max user processes (-u) 709
    virtual memory (kbytes, -v) unlimited
