[TYPO3] Server crash after importing t3d file

[Sandy Matheson]

I am posting this for information to anyone who may find it in the
future.

We have just migrated an old Typo3 installation to the latest version
(using the starter package from the Web Empowered Church WEC). THis
was done by installing and configuring the new Typo3 installation and
then importing a t3d file of the previous website structure.

When this went live it resulted in a server crash taking down all
websites on the same hardware platform. After many hours of
frustration the problem was very simple - as it often is!

The t3d file from the original website strucutre included a Typo3
domain record. When this was imported it resulted in two separate
domain records for the same domain at different places in the page
tree. When the url was accessed this resulted in Typo3 attempting to
resolve the domain to two separate places and this resulted in am ever
increasing number of unresolved http and sql processes that crashed
the server.

If anyone finds this in the future ensure you delete the Typo3 domain
record from the imported t3d file.

I hope this information helps someone else.
