This could be due to some resource limit, either on the server itself (or) specific to your user account. Limits in your shell could be checked via ulimit -a. Esp check for ulimit -u max user processes, if you have reached max processes, fork is unable to create any new and failing with that error. This could also be due to swap/memory resource issue

    fork: Resource temporarily unavailable




    The error means that the current shell resource is limited (check the limits by ulimit -a). So you can either try in another shell, or increase the resources by using ulimit command which controls over the resources available to the shell and processes it creates on operating system.



    To increase the limits, try running:



    ulimit -Sn unlimited && ulimit -Sl unlimited


    to raise the soft limits to hard one, or:



    ulimit -l unlimited
    ulimit -n 10240


    to set the maximum size a process to unlimited and the maximum number of open file to 10240.



    See: help ulimit for more information.



    To make it persistent, add the above settings into your startup rc files (e.g. ~/.bashrc).




    You can also use /etc/sysctl.conf (see: man sysctl.conf) to increase the kernel limits, e.g.



    kern.maxprocperuid=1000
    kern.maxproc=2000
