LIMIT THE PROCESS
We can create a htacces file on his home directory and limit the process with the "RLimitNPROC 20 " line, in that case if he is using more than 20 process he will get a 500 error on this domain. Or we can monitor the server with the top command and check the process which is taking high load and kill it. If the account cause for a high load again we can go ahead suspend him.
EMAIL ISSUE WITH YAHOO
Now a days yahoo strictly recommends SPF, Domain key and Dkim for incoming mails to their servers, along with this yahoo need to approve or white list your mail server IP's in their servers, for that you need to fill the form and get approval from yahoo, normally it will take some time. Thank you for your patience.
I could see that the mail server IP is still blocked by yahoo. Also I could see the SPF and domainkeys are already set for your domain.You need to contact yahoo to resolve this issue, once yahoo white list your mail server IP 64.120.214.206 the issue will get resolved.

MYSQL LOAD ISSUE --- AN EXCEPTION TO LINUX WORLD
I have tweaked mysql and apache in the server for better performance, but the cpu load for mysql still remains same. On digging this issue deeper,I can see from the mysql process list that the database "betsexp1_main" is hitting a certain query "copying to tmp table" message to a very long period of time. For fixing this I have repaired the tables and also changed the value of tmp_table_size, unfortunately that doesnt help. What we need to do is to check and optimize the code and database associated to your site. Please have a look with your webmaster and optimize it.
CPANEL ChekServd EMAILS
Chkservd is a service running on Cpanel servers. chkservd service monitors other services, if any of the service which is monitored by it is found down, chkservd will restart the service automatically and notify server admin. I could see that all the services are running fine in your server now. You can verify this from your WHM via " main >> Server Status >> Service Status" also you can safely ignore this mails. Feel free to contact us if you need any further assistance.
MEMORY OVER USAGE PRIVMPAGES
We could see privvmpages parameter is hitting it fail count limit, must be the reason you are having cpanel accessibility issue.
The privvmpages limit is hit when memory over usage occurs, temporary solution is always reboot vps, perememnat one is to see which application is using up memory and rectify it or upgrade ram

ABUSERS IN OPENVZ
===================
Yes, SolusVM provides bandwidth graphs for each VPS and the node in general.
Just go to Nodes >> Manage your node and you will see the graphs.
Other than that it's best to keep checking the processes that your clients run to detect the abusers.
NAMESERVER UPDATION WITH DOMAIN REGISTRAR
===========================================
Please note that every registrar has a different process for creating private name servers. The only way to create Name Servers is by using the IP addresses we assigned to your ns1 and ns2.yourdomain.com You will not be able to change your sites DNs to private name servers until your private name servers are registered with your domain registrar. Some regsitars don't even have an option for you to create private name servers on our own. In many cases emailing them to do it is the only option.
If you can provide me the login details I also can assist you in this, other ways you may need to contact them.
GODDADY NAMESERVER REGISTRATION
=======================================
For setting up your domain "domainname.com", you may please register the private name-servers at the domain registrar end (godaddy.com) with the following details
===
ns1.domainname.com 173.212.249.26
ns2.domainname.com 173.212.249.26
===
If you found any issues registering private nameservers, please follow the steps pasted below to setup the private NS
1.Go to Domains >> My Domains
2.Click on your domain you'd like to set up private nameservers for
3.Click on (add) under 'Host Summary' on the bottom left.
4.For "Host Name:" you'll input "ns1" (no quotes) in the box.
5.For "Host IP 1:" you'll input your primary IP address(173.212.249.26). Click "Ok" - Your first nameserver has been created.
6.Click on (add) under 'Host Summary' on the bottom left again.
7.For "Host Name:" you'll input "ns2" (no quotes) in the box.
8.For "Host IP 2: you'll enter the same IP(173.212.249.26) as your primary address, except one number higher. Click "OK"
Once this has been setup, please change the name-servers of the domain domainname.com to "ns1.domainname.com" and ns2.domainname.com". Please allow 2-24 hours for the DNS propogation to complete over the internet and after the specified time, your domain will resolve to our server.
SPAM ISSUE
===========
We have fixed the mail relay issue by repairing the "eximstat" database and restarted tail watchd. Now mail re-layers are showing correctly.
While checking the mail headers I can see that all these mail are send from the default mail account of the nutracis account.
By default all unrouted email will be directed to your main mailbox, where it will use disk space and resources of your account. This means that someone can send to anything@nutracist.com and you'll still receive it to inbox@nutracist.com (where inbox is your Cpanel username). This is how spammers send out mass messages as well as viruses.
I have now set it to "fail" for nutracis account. Pasting the steps below:
>> Login to your Cpanel, click on Mail, Default Address, at the bottom click Set Default Address
>> Select the domain in the drop down menu, I recommend repeating this for all domains listed.
In the to: field - enter :fail: no such address here
>> Click on Change to save your changes.
Also as an additional security I have reset the cpanel password of nutracis to Uy76nGysi9P
General Answer about VPS server
============
There's really no way for us to know if the plan would be sufficient for your needs or not. You'd be in a better position to know that. While our game server plans are designed to be more suitable than our hosting VPS plans it is still a shared resource system. If the CPU or I/O load from your application is too high and creates problems for other clients you would have to adjust that by either lowering the resource usage or moving to a product better able to support your requirements.
Not every application is suitable for a shared resource system, sometimes a dedicated server is the required solution.
Our general rule of thumb is that your resource usage should fall within the same parameters as 95 percent of our clients on similar or matching plans.
=================================
HACK PROTECTION
================
* Always use alphanumerical passwords and change the passwords frequently including (cpanel or other panel) password.
* Keep scripts up to date- You should always keep your scripts updated to the latest stable version. Many new script releases contain security patches so it is very important to always upgrade.
* Use trusted scripts- Use scripts from trusted developers that have a good track record of maintaining and updating their scripts.
* Use secure permissions- Never use permissions 777 on folders or 666 on files.
* Remove stuff you are not using- A very common source for account exploits is abandoned scripts which are not updated. Clients often install scripts for testing and forget about them, which are subsequently exploited and used to hijack the entire hosting account.
* Disable Anonymous FTP accounts
