Identifying the Cause
Several factors can contribute to the “Too Many Open Files” error:
- Inefficient Resource Management: Poorly written applications or scripts may fail to release file descriptors after use, leading to a gradual accumulation of open files.
- System Limits: The system may have conservative limits set for file descriptors, which can be exceeded under heavy load or when running multiple processes concurrently.
- File Descriptor Leakage: Some applications may have bugs that cause file descriptors to leak, consuming system resources over time.
