    If you find Linux is unable to allocate memory for java.io.ioexception = 12, this user guide can help you. If you hit error = 12, Unable to allocate memory or error = 12, Not much space, it means your system ran out of memory or swap space when Java tried to fork the process. The problem is how Java allocates memory while processes are running. When Java is executing a process, it may need to fork () to execute exec ().

     

     

    I cannot run a simple Java application that starts a process on my system. I don’t know how to solve this.

    When running Fisheye Git, it uses my fork system call, which temporarily allocates the same amount of memory to the Git process as my Fisheye JVM. The Git process never actually uses memory, but the system call fails if the operating system cannot provide it.

    Resolution

    You can try to allow Linux to overwrite storage devices with the command ‘echo> first / proc / sys / vm / overcommit_memory’, but there may be a bettere improve the allocated paging space. In general, you should reduce the heap value to what Fisheye really needs. Increasing it will only exacerbate this obstacle.
