apache拒绝响应、超时,救命!

apache拒绝响应、超时,救命!

最近我网站流量一上去apache就响应缓慢或者拒绝响应,网页要么打不开要么打开很慢,但系统资源占用没有异常。一天下来查了所有日志没有发现异常情况,请问各位大侠会不会是apache设置问题?谁有过类似状况的?
我是apache 1.3.36,系统centOS
谢了
顺便说流量下来后apache恢复正常
修改并重新编译apache-1.3.x,然后在httpd.conf中调整MaxClients大些。apache-1.3.x默认最大允许256个并发。对流量大些的站点显然是小了些。
昏这是我的服务器默认设置:
#
# Limit on total number of servers running, i.e., limit on the number
# of clients who can simultaneously connect --- if this limit is ever
# reached, clients will be LOCKED OUT, so it should NOT BE SET TOO LOW.
# It is intended mainly as a brake to keep a runaway server from taking
# the system with it as it spirals down...
#
MaxClients 150

可能是设置小了,是直接改大还是重新编译apache?我的apache是系统自带的

还有对于每小时流量2万的站大概设置多少合适?
直接改到750,问题似乎解决了,谢谢
