Mattermost 10.5.9 SEGV on LX Alpine 3.21.3 image #519
Description
Our Mattermost instance has long run in an Alpine LX guest. I need to upgrade it, but I'm having trouble getting newer versions to run. I eventually determined that util-linux breaks guest boot. Now on to the current problem, which is segfaults from the mattermost binaries. Current setup is:
Platform 20240208T000334Z
Alpine base image c38b1b62-6d89-41f1-bd1d-5342b2d783d7 alpine-3.21.3 20250407
Mattermost 10.5.9, official build
These packages (and whatever dependencies came along) are installed on top of the base image:
- bash
- git
- libc6-compat
- netcat-openbsd
- net-tools
- nginx
- openssl
- procps
- rsync
- shadow
- tar
strace output attached. I have a core dump I can make available privately, ~150 MB.
Unfortunately, mdb doesn't seem to produce much of value, though I imagine that's not much of a surprise in this environment:

Let me know what additional details I obviously should have included here. :)
