Hi,


thanks for all the support from this list and to my mail address.
The cause for the segfaults was a global registered $r in the  
PerlLogHandler - Script.

sub handler {
        $r=shift;
        $r->connection->pool->cleanup_register( "Apache::DBILogger2::logger" );
        return Apache::OK;
}
sub logger {
        my $s = $r->server;
        my $c = $r->connection;
        # $r was taken globaly...

With increasing load on the webserver sometimes the contents of $r  
was overriden during the logging action. Seems like a typical thread  
safe problem.

Instead of  clean_upregister now I use push_handlers to invoke the  
logging code.

sub handler {
        $r=shift;
        $r->push_handlers(PerlCleanupHandler => \&logger);
        return Apache::OK;
}
sub logger {
        my $r = shift;
        my $s = $r->server;
        my $c = $r->connection;
        # ...
