single PHP process use lot of system resources

[rnc]

hello
i have a issue on one of our directadmin server that running Centos 64bit

the problem is every day a php process is created on the name of one of our user and it take lots of server resources

12369 username 28 8 254m 4692 3320 R 49.9 0.1 2278:15 php

and if i dont kill it it may be become two process afew hours later

this user is normal user and when i kill this process this will not created in next hours
the main user usage of hosting service is running WHMCS and he activated cronjob

but i dont think this a cronjob process because the cron job is at midnight but this process could create ant any time

serve rhave php 54/53 installed
54 as suphp and 53 as fastcgi

how could i prevent such process to dont eat server resources and automatically terminate after a specific time ?

Hello,

You probably should either use CSF/LFD and configure it kill suspicious processes or investigate the issue with trace or /proc/<pid>/ and make a decision on what to do with it.
