    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 ().

    When someone got error = 12, Unable to allocate memory, or error = 12, Not enough space until it means your system is out of memory or space to swap when Java tried to track down the process. The problem is how Java best allocates memory when executing procedures. When Java is executing a process, it must fork () and then exec ().

     

     

    Symptoms

    When trying to expand a Git-A repository to Fisheye, the following memory-related error often occurs:

    Cause

    When running Fisheye Git, it can use the fork system call, which can temporarily allocate the same amount to the Git process that would normally be attached to the memory used by the Fisheye JVM. Again, the Git process will never use it, but the system call will definitely fail if the operating system cannot provide it.

    Resolution

    linux java.io.ioexception error=12 cannot allocate memory

    You can try rebooting Linux from the command line echo 1> / proc / sys / vm / overcommit_memory, but this task may be preferable to free up most of the increased allocated paging space. In general, you should reduce the size of your weapon to what the fish-eye really needs – enlarging will only exacerbate this problem.
