This sounds to me very much like you've got the mod_php loadable object linked against an incompatible version of a shlib which apach+mod_ssl is also linked to. At a guess: i) I'd finger the OpenSSL libs as a prime suspect: particularly if you've also installed OpenSSL from ports. It's not necessary to install OpenSSL from ports as the version in the base system is perfectly OK. ii) Different threading libraries can have similar bad effects. Everything should be compiled using the same threading libraries: if necessary, use /etc/libmap.conf to force the issue. (Although I've never heard of that being necessary for any variant of apache before now) The reason your kludge works would be to do with the order of resolving the required shlibs: something like one shlib resolves all the required symbols, but the other one is missing some. Use ldd(1) to investigate what shlibs a binary needs, and check for conflicts: % ldd /usr/local/sbin/httpd /usr/local/sbin/httpd: libz.so.2 => /usr/lib/libz.so.2 (0x280b3000) libssl.so.3 => /usr/lib/libssl.so.3 (0x280c1000) libcrypto.so.3 => /usr/lib/libcrypto.so.3 (0x280f0000) libaprutil-0.so.9 => /usr/local/lib/apache2/libaprutil-0.so.9 (0x281ed000) libexpat.so.5 => /usr/local/lib/libexpat.so.5 (0x281ff000) libiconv.so.3 => /usr/local/lib/libiconv.so.3 (0x2821d000) libapr-0.so.9 => /usr/local/lib/apache2/libapr-0.so.9 (0x2830b000) libm.so.2 => /usr/lib/libm.so.2 (0x28327000) libcrypt.so.2 => /usr/lib/libcrypt.so.2 (0x28343000) libc.so.4 => /usr/lib/libc.so.4 (0x2835c000) % ldd /usr/local/libexec/apache2/libphp5.so /usr/local/libexec/apache2/libphp5.so: libcrypt.so.2 => /usr/lib/libcrypt.so.2 (0x28266000) libm.so.2 => /usr/lib/libm.so.2 (0x2827f000) libxml2.so.5 => /usr/local/lib/libxml2.so.5 (0x2829b000) libz.so.2 => /usr/lib/libz.so.2 (0x2838e000) libiconv.so.3 => /usr/local/lib/libiconv.so.3 (0x2839c000) Cheers, Matthew -- Dr Matthew J Seaman MA, D.Phil. 26 The Paddocks Savill Way PGP: http://www.infracaninophile.co.uk/pgpkey Marlow Tel: +44 1628 476614 Bucks., SL7 1TH UK
