This started happening since a few days ago, and I am pulling my hair because I can’t figure out what is causing this. The server is working fine, but it seems to have slowed down because I see that the website is not as responsive as it was before (there is only one bigger website on the server). The cron jobs take 3 times as much to execute as before, and when I try to connect to the server by SSH, it takes a while for me to connect. All in all, things have slowed down in general. The weirdest things though is that CPU and memory usage are actually low and within the boundaries where they were before this started occurring. The bandwidth also seems to be in the normal boundaries.
I am checking the processes running, and I see that Apache and MySql take up most of the resources as before. But again as before, they are in the normal boundaries.
I am really baffled by this and I really don’t know what to do any more. Could someone please help as this is a very important server for me?
FYI, I am running Cent OS 6.5 x64. Thanks!
