首先感谢你帮助…
Apache崩溃并获取日志文件，我该如何解决这个错误？
在/ var /日志/的httpd / error_log中
... ... [mpm_prefork:emerg] [pid 19347] (22)Invalid argument: AH00157: Couldn't add listener to pollset; check system or user limits ... ... Apache版本
Apache/2.4.10 (Unix)
ulimit -a

在/etc/security/limits.conf

免费-g
[root@ns ~]# free -g total used free shared buffers cached Mem: 62 60 2 0 1 38 -/+ buffers/cache: 20 42 Swap: 1 0 0
我解决了这个问题。
“在内核3.2.9到3.2.17的epollpath上有一个任意的限制（1000），导致apache在1001+进程中死锁”

解决scheme：更新你的内核
最好的祝福
