Crash in long-running web process: Itimer: read(timerfd) failed

Summary

When running a Haskell process in a set of Kubernetes-style provisioned VMs, we've encountered VM instances that encounter this error:

semanticd: internal error: Itimer: read(timerfd) failed
    (GHC version 8.8.1 for x86_64_unknown_linux)
    Please report this as a GHC bug:  https://www.haskell.org/ghc/reportabug

As per the above, I'm filing this (though it doesn't happen reliably).

Steps to reproduce

I apologize, but we haven't determined circumstances that reproduce this crash. I will update this report if this changes.

Expected behavior

Not crash.

Environment

• GHC version used: 8.8.1

Optional:

• Operating System: virtualized Debian stable
• System Architecture: x86
