[MariaDB discuss] Re: Migrate MySQL5.7 to MariaDB 10.4, then to MariaDB 10.11 Failed

Hi Edwin, It looks like one of the *.frm files is causing the crash. These files contain the MySQL or MariaDB table definition (as in SHOW CREATE TABLE). The serialized binary form is being converted to a memory object that is called TABLE_SHARE. In the InnoDB storage engine, there is a set of data dictionary tables that partly duplicates this information, but they do not seem to be the issue here. I would hope that the mysqld.dmp file contains enough information to identify the problematic *.frm file. If you shared the file with us, it should be possible to diagnose and fix the parsing problem. Best regards, Marko Mäkelä
