Hello, I'll need more infromation about the issue. -- 1) I assume you have standard, up-to-date, F28 installation. You haven't done any kernel changes (recompilation) or modified the kernel flags. If you did, please list them here. You can find the running kernel parameters in "/proc/cmdline". 2) Please, give me also the kernel packages versions. $ dnf list installed | grep kernel Which kernel version do you run? 3) Is the isse reproducible, or it happened only single time? 4) Can you please install mariadb debuginfo packages on the affected system? 5) I assume no other suspicious lines were found in systemd journal or the mariadb logs. Where in the log can the line be found? (at which time, related to the startup that occured?) 6) The following shouldn't happen, but can you please check the library has satisfied all dependencies? $ ldd /usr/lib64/libmariadb.so You can also run in verbose mode with "-v" parameter and attach the output as a file to this bugzilla. 7) Can you give me please the configuration of mysqld? $ mysqld --print-defaults 8) After the segfault, I'd expect a coredump to emerge. Is there any related? $ coredumpctl 9) What were you trying to do? Just starting the service or running your application? Does that application utilize any server or client authentication plugin? 10) In case there are some plugins or storage engines configured by default, but you don't use them, can you please disable them in the configuration?

> And we have to run an old kernel, because 4.16+ kernels do not work stable under xen anymore. > 5.0.x kernels do not even boot, because xen bootloader are not able to load them anymore. That sounds like bigger XEN & kernel issue to me. Do you also have bug(s) filled against those two? Can you past the numbers here, please? Do you watch fedora mailing lists or the upstream projects (XEN, kernel). I'm rather uninformed on the field of XEN virtualization. I'd prefer to discuss the issue with devs or maintainers of the respective packages. It doesn't seem to me like a MariaDB upstream material too. I'm not going to file an upstream bug yet, unless you disagree with a more depth explanation, so I can start on something.
I have an identical error on my physical server.

This message is a reminder that Fedora 28 is nearing its end of life. On 2019-May-28 Fedora will stop maintaining and issuing updates for Fedora 28. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '28'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 28 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 28 changed to end-of-life (EOL) status on 2019-05-28. Fedora 28 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
