Occasional program crashes on ubuntu20.04

Expected behavior

[what you expected to happen] Running well

Actual behavior

[what actually happened] crashed

Steps to reproduce

This is a quantification program running on swift vapor. It crashed suddenly after running for a few days, and the phenomenon could not be reproduced immediately.

If possible, minimal yet complete reproducer code (or URL to code)

[anything to help us reproducing the issue]

System & version information

Please provide at the very least your operating system and Swift version information.

Ideally, run

scripts/nio-diagnose -o nio-diagnose.md PID_OF_YOUR_NIO_PROGRAM

and attach (or paste) the resulting file nio-diagnose.md into this bug report or send it to the SwiftNIO maintainers privately.
