MongoDB Percona Server for MongoDB

Summary

Percona Server for MongoDB 8.0.17 (aarch64) crashes with SIGSEGV approximately 60 seconds after startup. The crash occurs in a background thread during
what appears to be the first WiredTiger checkpoint. No errors in mongod logs — the process dies silently.

Environment

  • Image: percona/percona-server-mongodb:8.0.17 (aarch64)
  • Image digest: sha256:f1170f8bf68d051816cd4d956ca1f6ee9885c6cf0e1e5db5dc00a137af3603ee
  • Host: macOS 26.x on Apple Silicon (M-series)
  • Container runtime: Podman Machine (tested both applehv and libkrun providers)
  • Broken guest kernel: 6.19.7-200.fc43.aarch64 (Fedora CoreOS 43)
  • Working guest kernel: 6.12.13-200.fc41.aarch64 (Fedora CoreOS 41)

Steps to reproduce

  1. Create a Podman Machine with Fedora CoreOS 43 (kernel 6.19.x) on macOS arm64
  2. Run the container:
    podman run -d --name mongo -p 27017:27017
    percona/percona-server-mongodb:8.0.17
    /usr/bin/mongod --bind_ip_all --replSet rs0
  3. Wait ~60 seconds
  4. Container exits with code 139 (SIGSEGV)

What works

  • Same image digest on Fedora CoreOS 41 (kernel 6.12.13) — no crash
  • percona/percona-server-mongodb:7.0.15-multi on Fedora CoreOS 43 — no crash
  • Reproduced by 3 developers independently on different Macs

Notes

  • The crash timing (~60s) matches the default WiredTiger checkpoint_wait=60 interval
  • Frames #0–#7 appear to be mongod’s own crash signal handler (recursing after the original SEGV)
  • The original fault is in frames #9–#13 in a background thread (created via pthread, per frames #14–#15)
  • Both rootful and rootless Podman Machine configurations are affected
  • This may be related to aarch64 LSE atomics or memory barrier handling changes in kernel 6.19
