Hi all, We just installed PHP 4.3.6 on FreeBSD 5.2.1 on some SMP machines and we are experiencing some weird problems.
The PHP processes are running as FastCGI under Zeus with these compile options: ./configure --with-curl \ --enable-sockets \ --enable-dbx \ --with-jpeg-dir \ --with-jpeg \ --prefix=/webdisk/local/progs/php/compiled/4.3.6 \ --with-imlib \ --with-mysql \ --with-gd \ --enable-fastcgi \ --with-config-file-path=/webdisk/servers/php \ --with-exec-dir=/webdisk/servers/php/exec-dir \ --enable-memory-limit \ --disable-force-cgi-redirect \ --disable-url-fopen-wrapper \ --enable-track-vars \ --enable-xslt \ --with-xslt-sablot \ --enable-inline-optimization \ --disable-debug \ --enable-sockets \ --enable-sysvsem \ --enable-sysvshm \ --with-ttf \ --with-freetype-dir=/usr/local/include/freetype2/ \ --with-zlib-dir=/usr/src/lib/libz/ \ --enable-gd-native-ttf \ The database backend is MySQL 4.0.18 and is run on a seperate dedicated server. Last night some problems occured - when we queried the databases for simple queries that _should_ return some rows (and worked minutes before) the database simply returned 0 rows. A restart og the mysqld and the php processes solved the problems but they return at random. I suspect that it is some weird problem with PHP / MySQL / SMP but I have no clue what can cause the problem. The old servers we used before the upgrade are all uni processor machines and we haven't experienced any similar problems on those machines. The sysctl for FreeBSD is set to: kern.ipc.shm_use_phys=1 (used on the old setup as well) Is there any issues with the mysql library under PHP that can cause the problems on the server - eg. not thread safe? I do hope that any of you have some pointers so I can get over this weird problem. Thanks in advance.
