#38333 [Bgs->Opn]: Seg fault on graceful restart

ID: 38333 User updated by: mail at dasprids dot de Reported By: mail at dasprids dot de -Status: Bogus +Status: Open Bug Type: Apache2 related Operating System: SuSE 9.3 PHP Version: 5.2.0RC2-dev New Comment: No, it must have something todo with PHP 5, because without PHP-Module or with PHP 4.4.3 it works great. And as I said, I am not the only one with this problem.
