Question: Is this normal behavior of an Application ?

[imechemi]

Apache stats:

I am noticing a gradual increase in the yellow line and it seems like it hits a limit every sunday. And then app starts throwing 404s in between

Although, the graph clearly says bytes per second. But the graph is giving me a hard time understanding the gradual increase and sudden drop. I will be grateful if someone can share some thoughts on this. Thanks

楼主的服务器是不是设置了定时重启apache服务？
