  2. Kernel panic - Wikipedia

    en.wikipedia.org/wiki/Kernel_panic

    After recompiling a kernel binary image from source code, a kernel panic while booting the resulting kernel is a common problem if the kernel was not correctly configured, compiled or installed. [8] Add-on hardware or malfunctioning RAM could also be sources of fatal kernel errors during start up, due to incompatibility with the OS or a missing ...

  3. Exit status - Wikipedia

    en.wikipedia.org/wiki/Exit_status

    In Java, any method can call System.exit(int status), unless a security manager does not permit it.This will terminate the currently running Java Virtual Machine. "The argument serves as a status code; by convention, a nonzero status code indicates abnormal termination."

  4. Zombie process - Wikipedia

    en.wikipedia.org/wiki/Zombie_process

    Generally, the only kernel resource they occupy is the process table entry, their process ID. However, zombies can also hold buffers open, consuming memory. Zombies can hold handles to file descriptors, which prevents the space for those files from being available to the filesystem.

  5. Linux kernel oops - Wikipedia

    en.wikipedia.org/wiki/Linux_kernel_oops

    After a system has experienced an oops, some internal resources may no longer be operational. Thus, even if the system appears to work correctly, undesirable side effects may have resulted from the active task being killed. A kernel oops often leads to a kernel panic when the system attempts to use resources that have been lost. Some kernels ...

  6. Foreach loop - Wikipedia

    en.wikipedia.org/wiki/Foreach_loop

    foreach is usually used in place of a standard for loop statement. Unlike other for loop constructs, however, foreach loops [1] usually maintain no explicit counter: they essentially say "do this to everything in this set", rather than "do this x times". This avoids potential off-by-one errors and makes code simpler to read.

  7. Orphan process - Wikipedia

    en.wikipedia.org/wiki/Orphan_process

    In other systems orphaned processes are immediately terminated by the kernel. Most Unix systems have historically used init as the system process to which orphans are reparented, but in modern DragonFly BSD , FreeBSD , and Linux systems, an orphan process may be reparented to a "subreaper" process instead of init .
