April 29, 2026 - In early 2026, MongoDB stopped working with Linux kernels 6.19+, leading to a new kernel-drama. I discovered it by accident after a system update, trying to start my usual MongoDB container and receiving a exit 139 exit code. The cause of the issue was less trivial than I thought, and I had ...

r/mongodb on Reddit: MongoDB(8.*) container/quadlet crashes on tumbleweed with 6.19.*
March 7, 2026 -
I'm running mongo 8.0/2 together with unifi on my tumbleweed system, via podman.
After an update, TW decided to switch my kernel from my -longterm version to 6.19.3/5, and my mongo started crashing after running for about a minute, without any clear log-entries, apart from a backtrace I cant seem to find in journalctl any more...
After i noticed the bootctl/uefi kernel eff-up, I restored my -longterm 6.12 kernel and everything is fine.
Is this Mr murphy just being very active on my system, or what?
