I've taken a look at CPU/Memory/MySQL Usage and noticed that one site is using 133% of CPU under "Domain" column and on the left of it there is only [php5].

Is it something to worry about? Could it be "spam" or something like that

Code:
optikehr	optike.hr	2.06	0.29	0.0
Top Process	%CPU 133	[php5]
Top Process	%CPU 36.0	[php5]
Top Process	%CPU 34.0	php5
