Segmentation fault (core dumped)
A program accessed memory it wasn’t allowed to, and the kernel killed it with SIGSEGV (exit code 139).
MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 listeners added
More than 10 listeners were added to one event — often a leak where listeners are added repeatedly.
C/C++: free(): double free detected / double free or corruption (out) — Aborted (core dumped)
Memory was freed twice or the heap was corrupted (buffer overflow, freeing a non-heap pointer), so glibc aborted the program.
java.lang.StringIndexOutOfBoundsException: begin 0, end 10, length 5
substring()/charAt() used an index outside the string.
The application was unable to start correctly (0xc0000005) / Exception code 0xc0000005 access violation
A program tried to read or write memory it doesn’t own and Windows stopped it — buggy software, bad drivers/plugins, security sof…
fork: Cannot allocate memory / ENOMEM
The kernel refused a memory allocation — RAM and swap are exhausted, or overcommit/cgroup limits block it.
Thread 1: EXC_BAD_ACCESS (code=1, address=0x0)
The app accessed memory it shouldn’t — a dangling pointer, released object, unsafe pointer misuse, a data race, or infinite recur…
java.lang.OutOfMemoryError: Java heap space
The JVM ran out of heap memory and garbage collection couldn’t free enough.
Killed / Out of memory: Killed process (Linux OOM killer)
The kernel ran out of memory and killed a process to recover — the program just prints “Killed” (exit code 137).
MemoryError (Unable to allocate X GiB for an array)
Python couldn’t allocate memory — the data is larger than available RAM or address space.
Blue Screen: MEMORY_MANAGEMENT (Stop code 0x0000001A)
Windows detected a severe memory-management error — commonly faulty RAM, unstable memory settings or a bad driver.
FATAL: the database system is in recovery mode
PostgreSQL crashed (often OOM-killed) and is replaying WAL to recover.
Two steps away (32)
Kubernetes: CrashLoopBackOff
The container starts, crashes (or exits), and Kubernetes keeps restarting it with increasing back-off delays.
RangeError: Maximum call stack size exceeded
A function called itself (directly or indirectly) too many times — usually infinite recursion.
The kernel appears to have died. It will restart automatically.
The Jupyter kernel process crashed — usually out of memory or a native library crash.
Kubernetes: OOMKilled (exit code 137)
The container used more memory than its limit, and the kernel killed it.
FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory
The V8 heap hit its limit — a large build (webpack, tsc, Next.js) needs more memory, or the app leaks.
Error: Unhandled 'error' event (events.js / node:events)
An EventEmitter (stream, socket, child process, server) emitted 'error' and nothing listened for it, so Node crashed.
Fatal error: Unexpectedly found nil while unwrapping an Optional value
Swift force-unwrapped (`!`) an optional that was nil, crashing the app.
Lambda: Runtime exited with error: signal: killed (Runtime.ExitError)
The function process was killed — almost always because it ran out of its configured memory.
Illegal instruction (core dumped) (SIGILL)
The program used a CPU instruction your processor doesn’t support — typically AVX/AVX2 in prebuilt binaries (TensorFlow, MongoDB…
java.lang.ArrayIndexOutOfBoundsException: Index 5 out of bounds for length 5
Code accessed an array index outside 0 … length-1.
java.lang.ClassCastException: class A cannot be cast to class B
An object was cast to a type it isn’t.
java.lang.ArithmeticException: / by zero
Integer division or modulo by zero.
The application was unable to start correctly (0xc000007b)
A program loaded a DLL of the wrong architecture (32-bit vs 64-bit) or a corrupted runtime library.
The application was unable to start correctly (0xc0000142)
A DLL the program loads failed to initialise — often after an update, with corrupt runtimes, or when a desktop heap/session limit…
Gradle: Expiring Daemon because JVM heap space is exhausted / java.lang.OutOfMemoryError: Java heap space during build
The Gradle daemon (or Kotlin daemon) ran out of memory compiling or dexing the project.
Error: listen EADDRINUSE: address already in use :::3000
Another process is already listening on that port.
Error: write EPIPE
Node wrote to a pipe or socket whose other end was already closed.
RangeError [ERR_CHILD_PROCESS_STDIO_MAXBUFFER]: stdout maxBuffer length exceeded
child_process.exec/execSync produced more output than its buffer allows (default 1 MB).
.NET: Stack overflow. / Process is terminated due to StackOverflowException
Infinite or very deep recursion exhausted the thread’s stack; .NET can’t catch it and terminates the process.
Thread 1: signal SIGABRT (app crashes with "libc++abi: terminating")
The app deliberately aborted — an uncaught exception, failed assertion or fatalError. The console above the crash has the real me…
Swift: Fatal error: Index out of range
Code accessed an array index that doesn’t exist — empty arrays, off-by-one loops, or data changing while a table reloads.
PHP Fatal error: Allowed memory size of X bytes exhausted
The script tried to use more memory than PHP’s `memory_limit` allows.
java.lang.NullPointerException
Code called a method or accessed a field on a reference that is `null`.
java.util.ConcurrentModificationException
A collection was modified while being iterated (even in a single thread).
Composer: PHP Fatal error: Allowed memory size of 1610612736 bytes exhausted
Composer ran out of memory while resolving or installing dependencies.
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
The kernel booted but couldn’t mount the root filesystem — usually a missing or broken initramfs after a kernel update.
System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown
The process couldn’t allocate memory — large in-memory data, leaks, 32-bit process limits, or container memory limits.
Redis: OOM command not allowed when used memory > 'maxmemory'
Redis reached its maxmemory limit and the eviction policy (noeviction) refuses new writes.
Blue Screen: IRQL_NOT_LESS_OR_EQUAL (Stop code 0x0000000A)
A driver accessed memory at an interrupt level where that’s not allowed — almost always a faulty or incompatible driver, sometime…
Blue Screen: CRITICAL_PROCESS_DIED (Stop code 0x000000EF)
A process Windows can’t run without (csrss, wininit, smss…) stopped unexpectedly, so the system halted.
Error 0x80070570: The file or directory is corrupted and unreadable
Windows can’t read a file because the disk, USB stick or installation media has corrupted data or bad sectors.
C++: terminate called after throwing an instance of 'std::out_of_range' — what(): vector::_M_range_check
A C++ exception wasn’t caught anywhere, so std::terminate aborted the program. what() tells you the reason.
