We are having a problem with on of our Apache/1.3.24 (Unix) PHP/4.2.1 mod_ssl/2.8.8 OpenSSL/0.9.6d webservers. The server is segfaulting 5x a day, sometimes more. Today it even produced a coredump. The problem raised a few months ago and we are researching this issue since but is driving me crazy. We have switched memory on the server with new memory and updated all ports that are used by the Apache and PHP server. We have compiled Apache with DSO support and build a static one with PHP and mod_ssl. Still a segfault a couple of times a day. We tried to get some more information by debugging the coredump but i'm not an expert on this. Could someone with some spare time (heh..) look at the following output and maybe email his or her thoughts? Thank you.
