apache2.2 启动问题:apr_thread_create: unable to create worker thread

apache2.2 启动问题:apr_thread_create: unable to create worker thread

大家好:

环境:

1、系统: rhel 5.1  2.6.18-53.el5

2、apache 2.2.6

现装完系统后把其他服务器上的 usr 全移植过来,现在myql,可以工作了。

问题:apache 启动后自动停止了,

报错:error_log:

[notice] Apache/2.2.6 (Unix) PHP/5.2.5 configured -- resuming normal operations
[alert] (11)Resource temporarily unavailable: apr_thread_create: unable to create worker thread

请教这是什么问题,在线等,你们回复。谢谢!
重新安装一个吧,
原来的配置文件还能用
