I upgraded my mysql servers to mariadb 5.5 from mysql community 5.1 and now I get this error:

Creating logical backup 00:00:00 ERRORS:
- Output of command: 'command is : bash -c '\"/usr/bin\"/mysqldump --opt --extended-insert --create-options --default-character-set=utf8 --single-transaction --flush-logs --user=\"USER\" --password=\"*****\" --host=\"198.XXX.XXX.XXX\" --port=\"3306\" --all-databases > \"/var/lib/mysql-zrm/webmysql4.peigov/20130719111514/backup.sql\" 2>>/tmp/zrm/jabIrHPUXa;echo $[PIPESTATUS[@]

- mysqldump did not succeed.

any help would be great thanks :)
