Does Plesk really use InnoDB?

[bartjenl]

I've got problems with InnoDB on my server. MySQL crashes after a while with InnoDB enabled and works perfectly with InnoDB disabled.

Only problem of that last situation is that all the Plesk tables are InnoDB-tables, so Plesk is unavailable when InnoDB has been disabled.

Does Plesk (7.5.3) really use the InnoDB-functionality or can I safely convert the tables to MyISAM?
