That's the issue that you need to track down. For some reason your  
Apache (or probably rather your PHP) crashes.

> - In the horde logfile there where some errors: ** HORDE [imp] PHP

That logic is wrong. A new version means new code that can cause  
completely different behavior in the used software stack and trigger  
completely different bugs in the same stack.
