Comment 0 for bug 896439

System: Ubuntu 10.04 server with all updates running on Linode VPS
MariaDB Version: '5.2.9-MariaDB-mariadb105~lucid-log'

innodb is disabled
default_storage_engine is Maria

After installing automysqlbackup from repo and running it manualy information_schema is backed without problems but next database (wordpress) causes problems.
MariaDB crashes and is restarted.

Problem is repeatable.

On other VPS with symilar system but other MariaDB version (5.3.2) and some configuration differences everything is running without problem.

Syslog fragment:
