    Hi,

    It seems like you hit some bug in MariaDB or Galera code. I think the best course of action would be to open a bug report in MariaDB Jira (https://jira.mariadb.org/secure/Dashboard.jspa) and see if they can help you debugging this issue further. If you'll open the bug report, please paste the link to it here for the reference and for further readers who may end up with the similar case like you have.

    Thanks,
    Krzysztof

    This could be because you hit a bug. It is also possible that this binary
    or one of the libraries it was linked against is corrupt, improperly built,
    or misconfigured. This error can also be caused by malfunctioning hardware.

    To report this bug, see https://mariadb.com/kb/en/reporting-bugs

    We will try our best to scrape up some info that will hopefully help
    diagnose the problem, but since we have already crashed,
    something is definitely wrong and this may fail.

    Server version: 10.3.10-MariaDB
    key_buffer_size=134217728
    read_buffer_size=131072
    max_used_connections=1
    max_threads=153
    thread_count=7
    It is possible that mysqld could use up to
    key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467398 K  bytes of memory
    Hope that's ok; if not, decrease some variables in the equation.

    Thread pointer: 0x7f13f00009a8
    Attempting backtrace. You can use the following information to find out
    where mysqld died. If you see no messages after this, something went
    terribly wrong...

    Trying to get some variables.
    Some pointers may be invalid and cause the dump to abort.
    Query (0x0): is an invalid pointer
    Connection ID (thread ID): 10
    Status: NOT_KILLED

    The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
    information that should help you find out what is causing the crash.

    We think the query pointer is invalid, but we will try to print it anyway.
