求助 apache搞坏了进程不会结束

cyberdog · 发表于 2011-3-11 09:51:10

不知道怎么搞的
apache进程不会结束了
服务器现在没有访客可以看cpu是99.9%idle 但系统占用真实内存2.30 GB 虚拟内存527.45 MB
若是开放访客会占内存到100% 系统负载会不断升高到当机像进了无穷回圈一样打结
有人知道怎么会这样吗?

明明没半个访客

[root@wwwserver ~]# netstat -n | awk '/^tcp/ {++S[$NF]} END {for(a in S) print a, S[a]}'
TIME_WAIT 8
ESTABLISHED 1

复制代码

但Apache就是一直在执行

小内存的机必须限制进程数，不然访问量一多，内存会暴的
