Description Hendrik 2019-05-01 22:14:54 UTC

Description of problem:

After upgrading Fedora server 29 to Fedora server 30 journalctl repeatedly reports errors in libmariadb.so.3:

May 01 -------- XXXXXXXX audit[3553]: ANOM_ABEND auid=4294967295 uid=0 gid=0 ses=4294967295 subj=system_u:system_r:dovecot_auth_t:s0 pid=3553 comm="auth" exe="/usr/libexec/dovecot/auth" sig=11 res=1

However, dovecot seems functional.

Comment 1 Marco Schmidt 2019-05-05 08:46:23 UTC

This issue has already been fixed in several distros, here is a link to the patch: https://github.com/dovecot/core/commit/3c5101ffdd2a8115e03ed7180d53578765dea4c9.patch

Not a problem of F30, problem existed in F29 too. I guess it was related to a MariaDB update early April. Getting auth-worker crashes since then but proper journal entries about those only after the upgrade from F29->F30.

Comment 2 Nicolas Berrehouc 2019-05-13 15:54:47 UTC

Same configuration and same problem.

Comment 3 Marco Schmidt 2019-05-16 19:15:32 UTC

Is it possible to switch to 2.3.6? The issue is fixed by now. We're still on 2.3.4 (F30), even F29 runs with 2.3.5.

Comment 4 Michal Hlavinka 2019-05-17 08:31:21 UTC

Dovecot can't be build with GCC9, https://dovecot.org/pipermail/dovecot/2019-January/114494.html upstream is already aware of this. Hopefully, next release will contain the fix.
