As I try to create a new object, I've got a <i>Fatal error : a database transaction in eZ publish failed.</i>
What can I do ?

Here's the SQL debug output (when I create a new Article):

Hi Nathalie,

Are you sure that only eZ publish db user accessing database in the same time? Do you use cluster solutions?

You have this error because of:

1. Operation has entered a lock queue
2. Operation could be heavily overloaded

Hi Lukasz,

I am the only ezpublish db user that acess to the ez database.
In the same mysql instance we have another database used by others users.

By the way, I'm the only developper who works on the ez database instance and the site is not opened to public.

Regarding your remarks, wich solution do you propose ?

The only possiblity we've found is restart Apache and Mysql but this pb occured twice in three hours so it's not satisfying.

New informations about our problem :

A - We have created a new class with three attributes
2 text line
1 object relations

B - we have created an object based on it and all worked fine.

C - We have modified the class adding attributes
2 XML blocks
1 text line

now the class is composed by
3 text line
1 object relations
2 XML blocks

D - we have created a new object based on this new version.
when we clicked on "add objects" for the object relations attribute, Apache crashed

E - we put the XML editor disabled
the edition of the object worked fine again.

Could someone try to explain us why we have to disable the XML editor to add a new object relation ?
Did someone already have this type of problem ?
As our client have paid for the XML editor, the solution that disable it is not satisfying.

PS : this problem occured 80% of trying.
That mean that for the other 20% Apache doesn't crash

PS2: please note that on WINDOWS OS, when the pb occures there is an Apache error window that propose us to send the error repport to Microsoft.
If we click on "don't send", eZpublish continues its work normaly.
On Unix this window doesn't appear so eZpublish is not able to continue its work, staying in an infinite loop.

I am running into the same issue with creating different content objects. The problems disappears for a little while after restarting mysql but then the problem returns. Does anybody know what could be causing this or how to fix. My SQL output is below:

Hi Jason,

I don't know if this will help you but we actually resolved our problem upgrading the Online Editor from 3.0 to 4.0.2

I think our problem was with table locks in MySQL. The problem seemed to go away when we added innodb_table_locks=0 to our my.cnf.
