Mariadb keeps crashing under windows
Im using Mariadb 10.4 with Win2019. Sometimes mariadb crashes. I dont know what to make of the mariadb.log is posted below. Does anybody know what to do?
2020-12-17 14:27:20 0x19ac InnoDB: Assertion failure in file D:\winx64-packages\build\src\storage\innobase\row\row0sel.cc line 3966 InnoDB: We intentionally generate a memory trap. InnoDB: Submit a detailed bug report to https://jira.mariadb.org/ InnoDB: If you get repeated assertion failures or crashes, even InnoDB: immediately after the mysqld startup, there may be InnoDB: corruption in the InnoDB tablespace. Please refer to InnoDB: https://mariadb.com/kb/en/library/innodb-recovery-modes/ InnoDB: about forcing recovery. 201217 14:27:20 [ERROR] mysqld got exception 0x80000003 ; 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: 10.4.13-MariaDB key_buffer_size=134217728 read_buffer_size=131072 max_used_connections=14 max_threads=65537 thread_count=9 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 136384 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.

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. Writing a core file at D:\MariaDB\data\ Minidump written to D:\MariaDB\data\mysqld.dmp
