导致错误原因多种,需要具体问题具体分析
1.使用mmcache模块在linux x86-64上有问题
2.由于php编译安装过程有问题,或者apache+php安装完成后,PHP又重新编译安装过,同时apache也重新编译就会产生这种现象.建议保留httpd.conf和相关配置文件后,重新安装一遍apache+PHP,注意先后顺序,如果还是会有这个提示,请更换php版本重装.
3.php的模块zend_extension和extension冲突
4.由于使用了APC造成的,这是这类op-code缓存优化软件共同的问题.建议用最新版本试试(http://pecl.php.net/package/APC).一旦出现,只能重起apache.
5. /tmp目录文件太多,删除后正常
6. 配置模式为worker, 改为prefork
7. ZendOptimizer-3.3.0与jdk1.7.0冲突
8. web访问的某些特殊文件造成的,检查access_log可以看到,删除文件
