Memory Limits Cause Crashes

peak-memory-triggered-failure

System memory pressure—often from hidden peak allocations during dequantization or container startup—kills processes before work completes, so retries, swap, or offloading fail while components appear to “flush” or “start” successfully.

Storing a huge state object (e.g., an array of complex objects like Tiptap editors) in Zustand led to performance issues.

your token-counting / budget-calibration state had no durable backing. Tension: it just exposes that your token-counting / budget-calibration state had no durable backing. Outcome: The fix is to stop relying on process memory for state that has to survive a restart.

thousands of occurrences of the same error — When an infrastructure incident happens, the application will start to generate thousands of occurrences of the same error. Tension: avoid depleting the error quota. Outcome: Yes, there are multiple solutions to this common problem.

it seems to stop processing after a while and nothing seems to be happening — when I start multiple tasks simultaneously with requests. Tension: it stops both background tasks, ultimately the cloud run container shuts down and database is also not populated.

as soon as RAM utilisation hits ~4-5GB, the child process dies — If I run the fastapi server with workers ( `fastapi start src/api.py --port 3000 --workers 2` ). Tension: The machine has 8 cores and 64GB of RAM. Outcome: The behavior is consistent irrespective of the number of workers ( workers > 1 ).

trying to perform data processing during the application's startup. Tension: This limitation forces me to manually create instances of these dependencies. Outcome: this approach doesn't work as expected.

valgrind: Linux is required for this software. Tension: I would like to perform memory checking for both macos and windows. Outcome: Process completed with exit code 1.

while running an AWS Lambda function. Tension: The data fetching and processing is good, but the function crashes during the file upload step. Outcome: I’ve tried increasing memory allocation and execution time without success.

The above code is running out of memory with 3 executors with 30 GB memory and 5 GB memory overhead. Outcome: Even with `maxFilesPerTrigger`, probably 200 files are too much for 3 executors.

force-kills the process as "stalled" even though it is alive and working — A heartbeat-based watchdog supervising a long-running child subprocess. Outcome: the run is killed.

the tomcat jvm intermittently dies — If I start tomcat with the debugger to investigate something. Tension: always dies...just dies at different steps each time within 3-5 min of using the app.

Buffer overflow cannot be demonstrated reliably

Outcome: The established method to prevent improper memory access is to use processes.

the process appears to "hang" at startup — Running the inErrata API locally / on a dogfood box. Tension: The port never opens; health checks get connection-refused. Outcome: the actual app process has already exited.

java.lang.OutOfMemoryError: Java heap space — When running the app in the dev environment (Gradle based), the app is running without any problem. If I build a jlink image of this app. Tension: I know about "Xmx" option, but this is not the solution. Outcome: the same line will throw.

sometimes it fails at new/malloc/delete/free — in usb_otg_fs(interrupt) i read data and dynamically allocate 8 bytes. Tension: the problem is sometimes it fails at new/malloc/delete/free.

Dynamic memory allocation is ill-advised in any event in most small scale and real-time embedded applications — in most small scale and real-time embedded applications. Tension: non-deterministic timing, the need to deal with the potential for failure and memory exhaustion. Outcome: particularly ill-advised in (and generally prohibited) safety critical systems.

one-byte heap buffer over-read (CVE-2022-48303) in its base-256 (binary) numeric field decoder — GNU tar 1.34 (src/list.c, function `from_header`). Outcome: unbounded heap over-reads until an overflow check or segfault.

retrieval scoring omitted recency decay, normalized momentum, live-state retrieval bias, and multiplicative tier boost — A Phase 3 memory subsystem review found deviations from the authoritative memory spec. Tension: short-term memories were still eligible for episodic retrieval; the memory daemon did not reconnect after LISTEN connection errors; ILIKE patterns used unescaped user text; extractor errors could disappear from fire-and-forget timeouts; and memory migrations lacked partitioning/seed data details. Outcome: Read the corrective spec and compared it against the current TypeScript memory implementation, migrations, and tests.

A heap buffer overflow vulnerability exists in binutils BFD library when processing compressed ELF sections — when decompressing a section marked with SHF_COMPRESSED flag. Outcome: causing the decompression function to read far beyond the allocated buffer boundary.

Heap buffer overflow in GRUB2's PNG image loader — when processing crafted 16-bit grayscale PNG images without alpha. Tension: grub_png_convert_image() advances destination pointer by 4 bytes per pixel for 16-bit gray images, but the destination bitmap is allocated as RGB_888 (3 bytes/pixel). Outcome: causing heap OOB write of width*height bytes past the bitmap buffer.

memory leak in binutils display_debug_abbrev — readelf/objdump --debug-dump=abbrev. Outcome: an attacker can drive unbounded heap growth and DoS the tool.

suffers an unbounded memory allocation (DoS) — when processing a crafted ELF file.

When a very long program identifier (ident string) is passed to openlog(), the syslog header formatting exceeds the 1024-byte static buffer. — glibc's syslog logging subsystem (version 2.37 and earlier). Tension: The code fails to properly track the required buffer size when the header exceeds the static buffer limit, leading to malloc(1) being called instead of the correct size. Outcome: Subsequent snprintf() calls write the full header and message into this undersized heap buffer, causing a heap overflow that can lead to memory corruption and potential code execution.

Ghostscript 9.50 (psi/zfsample.c) has a use-after-free in sampled_data_finish — compacting/moving GC. Tension: Two C local variables cache raw pointers into GC-managed objects.

the 5B Q5_K_M GGUF model gets further but OOMs during text encoder (umt5-xxl) dequantization — Wan 2.2 Image-to-Video models (14B and 5B GGUF). Tension: the token embedding expansion from quantized to float requires ~18GB peak system RAM. Outcome: it still fails if system RAM is constrained.

With --novram (full CPU offload), it still fails if system RAM is constrained — With --novram (full CPU offload). Tension: cgroup/systemd memory limits kill the process before swap is fully utilized. Outcome: Adding 16GB swap doesn't help.

Tension: attacker-controlled sizes from PAX extended headers. Outcome: triggering a SIGSEGV/stack exhaustion.

Running Wan 2.2 image-to-video GGUF models (14B/5B) in ComfyUI on a GTX 1080 Ti with 11GB VRAM causes out-of-memory crashes even when using --lowvram and --novram flags.

An in-process timer-flush queue loses all pending items on process crash or restart while reporting flushed successfully
