求助:debian40r3+apache2+php4+mysql5+cacti0.8.7b

zorro2005

安装debian系统后使用:
apt-get install mysql-server php4-cli php4 php4-mysql php4-snmp rrdtool snmp   
系统会自动安装apache2-mpm-prefork,开始按照cacti指导文件安装并完成cacti, 能正常监控流量,但是过一两天后通过SSH或WEB访问服务响应非常慢,请各位大侠告诉小弟如何去分析解决此问题,另CACTI高手请留个联系方式,谢谢.

没人能告诉我怎么分析吗?重装了两次系统情况还是一样,自己顶起
ps -ef查看出现掉死的apache进程,关机时mysql有时会结束不了,只能强行关机,重启后又能正常工作1~2天,每次出现这种情况,使用任何命令如:top\uptime\ps等就会卡在那里,不会显示结果,不知道有没有其它方法能查找原因,如需日志的大哥请出下声,谢谢

每次通过WEB访问服务器,内存都会一点一点的慢慢增长,直到用光.

暂进解决办法为强行释放cached占用内存

另请教: 通过串口显示debian启动信息

现在在我能做到: 开机启动后串口终端显示操作系统选择菜单,选择debian后就没有显示了,等一会到login系统的画面,终端又可以显示并可以使用用户登陆.

是否需要硬件支援或编译内核支援将启动信息重定向至串口, 请赐教.
