If nothing has changed from quite a while on your VPS then it must be another VPS on the host server your VPS is residing on. A VPS if swapping extra resources from the host server thus affect the performance of other VPS'es residing on it. I would have checked the VPS resource usage first and the error logs and then forward all the details to the hosting provider to check if another VPS on the host server is causing issues.
The Emails you are getting are completely normal. But you need to worry about it when they comes over and over again. If you have a OpenVZ VPS, probably another user in the same node as you are in is using too much of resources. So you'd better contact your hosting provider and ask them to move you into another node which has less load than the current one.
i have told them this - it happens all the time now, atleast once a day grrrrrrrr latest email from them is this,
If the hosting provider isn't a much help, have a Server Management company OR a System Admin to look into it for you. BTW, what your hosting provider is saying is correct, if a one of the other VPS was taking extra resources, it would affect the performance of all our other VPSs, not just yours. So I guess it's time to check your own VPS more thoroughly.
I guess I have already sent you the commands a couple of days ago. If you are not comfortable with the Linux Command prompt, then you should better contact a server management company OR a sys admin as said above.
If you consistently experiencing down-time and you know for a fact that your sites aren't causing the issues, then it is most definitely one of the other VPS users on that physical server that is causing the issue. Your web host should outline the core requirements that VPS plans can use. For instance, being able to use a percentage of RAM/CPU for a sustained period. It would seem that a particular user or users are exceeding their allotted resources and the provider doesn't seem to be doing much about it. How long have you been with this company? Did the issue just appear recently or have you been battling this for a while?
