CPU spikes

I just did a search for a solution to this but all I could really find was lots of people experiencing this issue but no real solution.

There was one suggestion by dolphin_jay who said the following:

If I remember right this is not in d7.0.0, but if you have d7.0.1 it has been applied in the update/new version. I haven't noticed anything better or worse, it seems the same, but I don't watch the resource stats 24-7 either.

Hi gameutopia

Yes I do have 7.0.1 and if anything, the spikes have gotten worse. I have also just moved to a VPS with the new 7.0.1 patch and my hosting company said that it's even wreaking havoc on that.

It needs to be sorted asap as at this rate I'll soon need a server with the capacity to answer the Ultimate Question of Life, the Universe, and Everything.

I just checked those 2 files and they have been applied via the 7.0.1 patch but that was obviously not the solution.

@AlexT......do you have any other suggestions?

@Andrew.......has this problem been given the attention and resources it really requires? You would think that with so many people mentioning this CPU spike problem from over a month ago, that this would have been resolved by now.

I am assuming that you have some sort of ranking system based upon urgency for the many bugs needing resolving. Would be nice to see what this list looks like.

Anyway, this spiking was the reason my site was suspended a couple of times as it caused the shared server my site was on to crash. Hence the reason I am now on a VPS. Saying that, the server my VPS is on is only 1 quarter full which will mean that as that server reaches maximum capacity, the problem should only get worse.

It doesn't look very professional when your site continually crashes.

Might I suggest you set up Boonex.com to simulate the inner workings of Dolphin and have the Simple Messenger running as well as a Chat Room. It might help push things along if Boonex.com was spiking too.

Just my two cents worth  :)

OK. This is not funny anymore. Just heard from my hosting company and they sent me this:

 /flash/XML.php?module=im&action=updateInvite&recipient=2484
You'll need to disable that.

Those show php processes running for 48 seconds
That is not regular and I strongly suggest looking into it
We've been forced to shut down the vPS as the CPU usage was taking down the entire server

So what does that updateInvite do? What functionality will I lose if I disable it?

Has anyone found a solution yet?

I had a similar issue with resource useage. My test installation was consuming over 8% of the CPU for periods of over a minute - a violation of my WSP's TOS (it's on a shared server). Our solution was simply to reduce the frequency of the cron. This seemed to satisfy them.

BUT I would hazard a guess that this will not help you.

It looks like an invite is being sent out to user 2484, but is failing for some reason - check your RayImPendings table to see if there are any messages for user 2484.
