    Stability of the Apache service. (centos)

    VPS Mdtyh on my site that I like Dan.
    Each half-site and after a while he gets himself up like Don. I get some time
    SWAP is very very high. I do not know why this happens with the 1 GB Swap left. I have 512 meg RAM and 15 GB of space.

    I first thought that perhaps the DDOS
    But I see that bandwidth and traffic is generally above 15 Meg in touch.


    The only thing I would suspect that cPanel VPS I get it I do not know exactly what the IO.
    I think it was a hard problem.?


    This time the top of my ssh

    Have you contacted your VPS host? It may be related to the node.
