Hi,

I’ve been using xwiki for a month now without problems. I use it as an internal tool with less than 5 users.

Yesterday I have started to have some problems when saving pages.  When I write a add text to an existing page or I write a new page I often (not always) have the following error:

Error number 3201 in 3: Exception while saving document Projects.xwikiPb
Wrapped Exception: Could not execute JDBC batch update
com.xpn.xwiki.XWikiException: Error number 3201 in 3: Exception while saving document Projects.xwikiPb
Wrapped Exception: Could not execute JDBC batch update

Nonetheless the exception I can edit and view the page. When I edit it, I have a similar exception but for the XWD_ARCHIVE column

When I delete the page I have another exception saying that the page does not exist even thought it is still displayed

When I restart Tomcat, the page is really deleted.

I am using:

- Tomcat 5.0 (same problems with Tomcat 5.5)

- MySql 5.0 (I check tables for corruption with mysql administrator and everything seems fine)

I tried the following to solve my problem without success:

- I already configured xwiki to support large attachments.

- I modified the hibernate.cgf file with the useServerPrepStmts=false option

- I tried with mysql 5.0 driver

- I checked for resource usage

Thanks for any help.
