I created a brand new server last night, using EC2 (Amazon) - used the official AMI of Ubuntu 10.10 from Ubuntu site ami-cef405a7  
Added Apache, PHP, MySQL (apt-get install)

Moved one domain which uses VBulletin to this server
This morning I have the same crash on this new server int he Apache error.log
