Jackrabbit - upload error

[Raquel Alaman, modificado hace 12 años.]

Hi,
We have a liferay portal 5.2.3 with tomcat 6 on two balanced nodes and jackrabbit as a repository. We developed a portlet so you can attach files (it's a simple cv form). The portlet works fine on developement environment (1 node), but not on pre environment (2 nodes). We can add files via Control Panel - Document Library.
The permissions are set (default-ext.xml documentlibrary.xml) to guests to add files. The files are saved in a MySQL database.

When trying to add a file, get the following error appears:
