Server UL7

[RaZor Edge]

Since 2 or 3 weeks, my VPS is having serious slowdown at certain time of the day. These slowdown seems to be related to high IOwait (wa) that cause high server load. (when iowait is high, server can't write on the disk easily so every task are put in queue... what cause serious slowdown and make the number of task go high)

My server load average for summer was always below 1.00 (around 0.40, 0.60 at rush time... 0.20 -0.30 at normal time). There's nothing new on the VPS right now, and my website is less busy during september and october than summer (since the beginning of school).

I've got a trouble ticket open about it (2356250) since 5 days, but here, all I want to known, is if others have similar problems.

(A problem like that have happen some months ago, and it took several weeks to dehe to finally solve this (the problem was unrelated to my particular VPS). There is no way my website can suffer from downtime and slowness again without losing a bunch of visitors - after all the problem there have been lately...)

My VPS is on server UL7.

I went through your ticket and checked the server and your vps and we have found some problems with the main vps configuration files in virtuozzo. We are fixing them right now. I will also reply in your ticket about the resource utilization of your vps.

Hi Veena,

As it seems impossible to send you a PM, can you please check this ticket again.

I would like to clear this up so I can decide what to do when it will be time to renew my contract with DEHE. Right now, the VPS seems really less stable that it was 1 months ago.

I want to understand why I have these problem now, when everything was perfect (for many months) some weeks ago.

My visitors keep report to me that my website is sometime frozen by server load of 10. It seems to happens frequently at 6:00am, when there was pretty no one on my website. At peak time, when my forum is busy (17:00/19:00) server load can be at 0.35... but in early morning... it is at 10.00. This seems pretty strange. (Note: The overall situation is better since you have made some change to the VPS configuration)

(Logs, stats and backups are deactivate on my VPS so it is not the cause).

The must be something that have cause all of this!!??!!

Thanks for your help.

Maybe we should look at moving his account to a new node? Im not sure if this is a node wide problem or not but if it just cropped up like he reports then we may be better off moving accounts and rebuilding and testing that node. But first just getting everyone off ul 7?

RaZor Edge,

Sorry about the pm, looks like it was disabled by default.
As explained in the ticket, your vps is using more than what is available for your plan, there are a lot of resource parameters hitting the limit and I have offered solutions via your ticket. Please follow up in the ticket.

Just to keep this updated. Since my last contact with support the problem I was refering to seems to have disapear and server load is back to normal.
