What can cause high amount of CPU/MEM in a shared hosting server?

[2 Grey Star Level]

I got notification from admin about high usage of CPU time. I killed a db which is doing auto rss parse. But I was told my CPU time is still high. The highest traffic I got on one of my sites is about 200 visits daily. I don’t think that would consume much CPU time in a shared server. Does anyone has experiences of high CPU time in your shared hosting account and how do you solve it?


Answer #1


there can be lots of reasons.

You should ask the admin which scripts/files are using the resources.

i’ve seen compromised accounts where php shells were leeching lots of cpu time since they were using it to send massive amounts of spam.

Hope that helps a bit.

Will be interesting to hear your report back on what you find.. The first thing that came to my mind is what Giovanni Madari had mentioned. Those spammers will suck as much bandwidth as they can. Which is interesting, you would think they would throttle their efforts to remain undetected. Ive had experience with compromised sites and the data analytics are always off the charts.

As Giovanni said, I would recommend asking the Administrator working the ticket to see if he can help narrow down what is causing the high cpu usage.
