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:

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