This error affects Confluence 5.3.1

Today I moved a page with around 50 child pages and very much links with circular references between the pages to another space.

After around 15 Seconds of waiting an error occured and has been displayed in the move dialog. Unfortunately I forgot the error message.

The result was that the page and all subpages were moved, but around 70% of the links (about 500 links!) were broken! I had to delete all these links manually and add them again.

I checked the catalina.out log but found nothing related to this error.

The priority "Critical" is suitable because of the resulting severe data corruption and inconsistency.

I assume the problem is only with so very much links. I often moved pages with Confluence with no error, but never a page with so much child pages and much links.
