When launching frequent cronjob part, I've got :
Running cronjob part 'frequent'
Starting notification event processing
Fatal error: A database transaction in eZ Publish failed.
The current execution was stopped to prevent further problems.
You should contact the System Administrator (firstname.lastname@example.org) of this site.
The current transaction ID is TRANSID-86dc94e5af5b2a31e6c5a6e54e774c43 and has been logged.
Please include the transaction ID and the name of the current script when contacting the system administrator.
Looking at mysql query log, I can see the following SQL query :
SELECT DISTINCT user_node.node_id,
FROM ezcontentobject_tree user_node,
WHERE user_node.node_id IN ( ) AND
user_node.path_string like concat( user_tree.path_string,'%' )
Steps to reproduce
1. Edit a node
2. Run "frequent" cronjob part
