Maybe you are receving a DDOS attack or any malicious script which is eating up the BW.

Do you have firewall enabled on CWP?

you need to check what you have running on your server this can be anything, mostly memcache, or host links on images/files/videos or big files

you would need to check logs and you can also monitor server via top to see if something is at the top of the load

bwm-ng

You would probably need to install this tools
iftop
iptraf

as soon as I enabled firewall high traffic is stopped,

thank you for answer, logs are looks like so mass,hard to understand, but in cpu usage I see memcache using alot source, but indeed in my sites I dont use it at all, and even I didnt install it, is it bug of cwp ? why memcache ports are not closed for outside connection by default ?

then you probably have memcache reflected ddos attack and you need to remove this ports 11211 from the csf firewall if you have it listed there
