The problem appears with different Clients (MSIE (Wins,Mac), netscape
(Wins,Macs,Linuxs)) and the certificate is from thawte.

We "solved" the problem by inserting an (for my understanding)
unnesseccary line:
SSLCACertificateFile /opt/apache13/conf/ssl.crt/ca-bundle.crt
in the global server config of apache.

By the way, we thought to rid ourselves of the problem already once,
but had to reboot the machine recently... To me this appears to be
some kind of server parsing or memory problem.

But I confess not to be a specialist in mod_ssl and apache internals.

Thanks so far.
