[statscheck] Stats/Server Overload
I've been receiving these emails since yesterday (received every 6 hours or so) titled
[statscheck] Stats/Server Overload on vps.xxxxxx.com
Basically saying that one of my account is running a very high CPU usage.
And when I checked the "top" command, I found that indeed one account is running about 50-90% CPU usage constantly.
I found that this happen only since the last 2 days.
Not sure whether it's the source of problem but from what I remember I only installed wp-mail-smtp plugin on that account's website.
I've already deactivated the plugin with no result, the CPU is still running high.
Can anyone suggest where should I start finding the main source of this problem?
Just FYI I'm running CentOS 6.4 and using WHM/Cpanel.
And here's some lines from the top command
top - 13:20:39 up 43 days, 12:58, 1 user, load average: 1.89, 1.79, 2.08 Tasks: 129 total, 3 running, 124 sleeping, 1 stopped, 1 zombie Cpu(s): 75.4%us, 24.6%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 1030628k total, 977808k used, 52820k free, 186932k buffers Swap: 0k total, 0k used, 0k free, 255264k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 13840 user001 20 0 40056 9504 4840 R 84.7 0.9 1647:12 php
Thanks in advance for any info.
