Server Load & cpsrvd - waiting for connections

[BizzHost]

Hi,

I have a QuadCore2 Server with 8 GB RAM
CENTOS 5.3 x86_64 standard
cPanel 11.24.4-S36281 - WHM 11.24.2 - X 3.9

The load on this server always remained below 1 even in peak hours.
Since last 1 day, the Load Average has gone up and hovering around 3.40. In the Process Manager, apart form user's processes it has started showing a process under root called "cpsrvd - waiting for connections", which is taling about 10% of CPU.

I have never seen this process before.

Can anyone please shed some light on this process and which connections it is waiting for.

I use CSF firewall on the server.

Thanks so much.
