Temporary Files Accumulating and Filling Disk Space
Your application creates temporary files for processing (image transforms, PDF generation, CSV exports, file uploads) but never deletes them afterward. Over days or weeks, these orphaned files accumulate and eventually fill the disk, causing the application to crash or become unresponsive.
This is a silent issue that doesn't appear during development or testing because the files accumulate slowly. In production, you first notice it when the server runs out of disk space, uploads start failing, or the database can't write its WAL files.
The root cause is that Claude Code generated the file creation logic but didn't include cleanup logic, error handling that cleans up on failure, or a scheduled cleanup job.
Error Messages You Might See
Error: ENOSPC: no space left on device
OSError: [Errno 28] No space left on device
Disk quota exceeded
write ENOSPC
Failed to write WAL: disk full
Common Causes
- No cleanup after processing — Files are created in /tmp but fs.unlink() or os.remove() is never called after use
- Error paths skip cleanup — When processing fails with an exception, the temp file is never deleted because cleanup is in the success path only
- No try/finally block — File cleanup isn't in a finally block, so any thrown error leaves the file behind
- Missing cron job — No scheduled task to clean up files older than a certain age
- Unique filenames every request — Using UUID-based filenames means no overwriting of old files, just endless accumulation
How to Fix It
- Always clean up in a finally block — Wrap file operations in try/finally (or use Python's tempfile.NamedTemporaryFile with delete=True)
- Use streaming instead of temp files — Pipe data between transforms without writing intermediate files to disk
- Implement a cleanup cron job — Schedule a task to delete files in /tmp older than 1 hour
- Set tmpwatch or systemd-tmpfiles — Configure OS-level cleanup of temp directories on a schedule
- Monitor disk usage — Set up alerts for disk usage above 80% to catch accumulation before it causes outages

Alvin Voo
I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

Caio Rodrigues
I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**

Get HelpFrequently Asked Questions
How do I find what's filling my disk?
Run 'du -sh /tmp/* | sort -rh | head -20' to find the largest items in /tmp. Use 'df -h' to see overall disk usage. Check your app's upload and cache directories too.
How do I prevent temp file accumulation?
Use language-specific temp file APIs that auto-delete (Python's tempfile, Node's tmp library with cleanup option). Always delete in a finally block and add a cron job as a safety net.
