Comment 1 for bug 1867937

What version of liberasurecode are you using? From the frag header dumps, it looks like 1.5.0, is that right? It looks like the fix for #1666320 (https://github.com/openstack/liberasurecode/commit/a9b20ae6a) first appeared in 1.6.0 -- if you're on an older version, can you try upgrading and see if that resolves the issue?

FWIW, if you for some reason *can't* upgrade but you *do* at least have some control over the env vars set when running swift, you should be able to use LD_PRELOAD to ensure all services are using the zlib crc. I'd strongly recommend upgrading though (potentially even building from source rather than using system packages).
