MongoDB, TCMalloc and RSEQ | Alessandro Miliucci
April 29, 2026 - In the following weeks, were created various tickets on MongoDB’s Jira. It only takes a few days before the origin of the problem is understood: it is related to changes affecting Glibc, TCMalloc, RSEQ and recent Kernels. Even external projects like Arch Linux are aware of the problem but find confirmation in the January 2026 kernel thread that it is a TCMalloc issue: therefore, it is not a kernel problem.

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?
