bind9 / named process very high CPU usage

**TechnikOnkel** · Nov 14th 2014

Hello,

i am using i-mscp 1.1.13 on Ubuntu 12.04 - 64 bit

Now i saw that the CPU usage is always very high.
"top" shows me the following:

Code

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
8757 bind 20 0 384m 23m 2808 S 95 0.3 4:44.02 named
9133 root 20 0 17332 1328 952 R 2 0.0 0:00.02 top

I already restartet the Server and bind process, but without any luck.
Does anyone know which log files can I check?

Thank you!

Hi TechnikOnkel,

Could you please provide the version of Bind/Named?
Use this command to find out: named -v

Have you changed any named configuration files manually? If so, please provide the changes.

Also, please check your syslog (/var/log/syslog) for named activity.

There are some bugs or configuration errors that could cause CPU hogs.
Also, I've had CPU/RAM hogs of bind in the past, caused by DoSses or faulty third-party test software. (check syslog for that)

For me, it's not an i-MSCP issue at the first look at it.

BTW: Update to latest version available if you want to get more support (1.1.16).

@TechnikOnkel

Do you are using the OwnDDNS plugin ?
