Segfault on webclient !

Sun Mar 1 21:10:57 CET 2009

Hi all,
now i am really out of options and so i consult you a state of the
last resort.
I really tried all debugging but things don't start to work.
Now after running 2 years without any probs (Updates of the machine a
distribution MADE ID NECESSARY TO UPGRADE KOLAB), but after 2 days of
work i give up.
I had severe troubles to get beta1 working (segfaults in postfix smtp
etc.) but now all in working except the webclient.
Apache segfaults before reaching the login screen.
I also tried with external apache+php and got  a little bit further
but didn't succeed anyway.
Current OS:
Debian Lenny amd64 (Host has 4 GB RAM and multigigE network connection).

Apache2 Debian Lenny:
On external client in can login but after the login succeeded the
Browser windows is blank.
The source rerfers to: (Get error 500 without a segfault of apache2
(lenny))

On kolab the apache segfaults bevor anything is loaded:

'--with-apxs2=/kolab/sbin/apxs' '--disable-cli' '--disable-cgi'

So i think, that --with-db4=/kolab should take the statically linked
libdb.a and should not open the wrong version from debian which is
4.6. Kolab uses 4.5 so could that be the problem ?
Linker Problem of apache-php ?
Any help would be very appreciated.

Kind  regards

P.S.:Now i know what it means: Never change a running system:-<
