    Re: High server load

    Just been told it's all ok now. Did a disk speed test and got 42.4 MB/s which is better than the 1.7 I had half an hour ago.
    Waiting to be told what the problem was.

    Re: High server load

    I've had no response from my original ticket (marked as "emergency") - sent 2.5 hours ago.

    If I was told "really sorry, we have a major issue but we are working on it" fair enough, but nothing. Problem is that when speaking with live chat I have to go through the same again each time and then they tell to send a support ticket in (arrggghhhhhh) probably because they have no clue.

    I've just rebooted and have a better load now, %wa still looks too high though.
    Would do a disk speed test but don't want to overload it until they've finished fixing.

    My disks are pretty much in use 100% which means that everything is waiting on the disks. Server is pretty much idle, loads of memory free. Seems like the same issue!

    Well, it may well be a network problem but it's manifesting itself to us as a disk issue.

    I agree there are some good people in support, I would just like a little more feedback so I can manage client expectations.

    Jane, you should work in the support department. More sense from that than I've had the past few months!

    That issue was raised directly after I sent in a support ticket after having a right load of rubbish from the live chat. Just get really frustrated at times, they have some great people there (like Oliver) but then live chat just seems to be... (leave you fill in the gaps).

    I asked if the cloud5 issue would be related to the disk issue I was having and was told no as it was a network issue!

    High server load

    Hi.

    We currently have a number of cloud based servers with EUKHost and over the past few months one of them is getting gradually worse, suffering from high load.

    Over the past few weeks I've transferred some of the bigger and more used web sites of it to try to easy the burden (most of the sites are test sites so clients can see the site before putting it live and so get very little traffic).

    Over the past few days been trying to see why the server is struggling so did a top this morning:

    top - 08:24:08 up 1 day, 14:24, 1 user, load average: 2.15, 3.34, 3.14
    Tasks: 198 total, 1 running, 192 sleeping, 0 stopped, 5 zombie
    Cpu(s): 0.1%us, 0.1%sy, 0.0%ni, 74.9%id, 25.0%wa, 0.0%hi, 0.0%si, 0.0%st
    Mem: 5993032k total, 2465552k used, 3527480k free, 91832k buffers
    Swap: 4128760k total, 2416k used, 4126344k free, 1079732k cached

    To me this reports that the memory is fine, the server is 75% idle but all of the processes on the server are in a waiting state (25%). Have run an iostat -x 2 5 and it shows this:

    This shows that the bottle neck seems to be the disks as they are pretty much 100% in use constantly.

    Having a hard time getting support to help on this, after I posted a support ticket about this I have now been told it is a network issue. Asked if this would affect the disks and they then said no. Arrgghhhh.

    Can anyone offer any help?
