    Hi,

    We have been having this issue since few weeks now and were unable to fix either by us or our linux sys admins HIRED to assist us...

    I am running CentOS7 on a VM and there we are osting our clients with cpanel + WHM, i have noticed from time-to-time all my clients domain become unreachable and whm itself too !!

    When i check our VM it was up and running but we had to reset the VM in order to access WHM back again and that was very frustrating for both us and our clients and unacceptable for many !!...

    We have requested our admins to perform server hardening (several times by different admins) but unfortunately this problem is getting even worse since 3 days exactly, one thing i did was to give that VM a dynamic memory ranging from 12 to 48 GB, and lots of CPU cores, to my surprise, i found that the VM went up to 41 GB of RAM and am 100% sure that's abnormal as we have less clients and no way they could consume those resources, by the time the VM consumes so much RAM WHM goes down and all our domains are unreachable, i suspect something is causing this huge usage, maybe memory leaks ? bots ? attacks of some sort ??...

    I would appreciate help in this regards as we are running out of time and effort trying to get to the bottom of this problem and so far we keep rebooting the server whenever this occurs that's all we can do !...

    Thanks,

    Hi,

    Did you check the connections to the server? When the WHM is unreachable, at that time, are you able to access the VPS? There are lots of possibilities to explore for investigation on this.. Do you have any firewall configured on the server?

    I don't need help from you besides i clearly said the VPS is accessible just fine, we have been with ur company for sometime and ur team seem to lack the enthusiasm or the well to read the client requirements CLEARLY one needs to repeat him self 10 times for your team to finally do the job. Also ur apparently after the money and spamming here and there wont get you respect either, so thanks but not thanks !...

    We did !... They were unable to help as they said everything seems normal, also several sys admins said the same and that's what drives me nuts !... I tried to create a new VM from scratch taking their advise it might be a node/vm issue, i admit the problem started to appear less often (to the point i thought it was fixed) but AGAIN this morning WHM down, this is pretty ridiculous matter and am not sure what to do about it, is it possible to have any sort of fix (reinstall OS, upgrade to cloudlinux maybe, different centos version, restore previous backup before the problem happened ??...) and what help can i seek here since all other methods have failed so far ??...

    Could you please post that cPanel Technical Support ticket ID here?

    Let's back up a moment.
    When this happens do ALL sites and server become unreachable?


    Could you please clarify this comment? What do you mean by "reset" exactly?
