Hello.  Some who used to work here installed your product, InstantForum.NET v4.1.3.  I don't know what kind of license or support we may own.  In any case the product is being used in production and it becomes intermittently unresponsive.  When it stops responding, if you login to the web server using an rdp session you can see you have established connections to the application from the output of netstat -an.  However the end users just get an hour glass.  If I stop and restart the forum web site from within IIS it seems to correct it.  It could be minutes, it could be hours and it stops responding again. 
 
Any suggestions?

It's all going tits-up. My site too is suffering badly. I checked the worker process out and it has connections open to instantasp.co.uk, and seeing as this site is suffering badly itself, it seems we have a knock-on effect of slowing down.

My site is almost unusable, and there's nobody from instantasp talking about these issues, no news and no response to my support ticket.

The fact that the forum software communicates or needs to call back to this site is unacceptable to me. I presume it's something to do with licensing, but it's just not acceptable that the performance or availability of my site depends on this one being okay. This is such a huge issue that I don't think it can be over-estimated. It is incredible to think that by targeting this one site, you can take down a multitude of other sites!

This is an issue that could cause me to look into migrating away from InstantForum. InstantASP, please respond to this and get it resolved asap! Remove this functionality and let us have our sites back!

Jay,
I'm looking into these issues this morning, the post was made on saturday, as such I've been looking into it since first thing this morning, currently it seems to be an isolated incident, however there has been no discussion or news thus far, because I've not completed looking into it, as soon as I have, as is usual on the forums, I will post a response. I'm sorry your ticket has gone unanswered, Before the close of business today I will look this up and follow up on why it has not been answered for you. 

First a few quick points:

1) Your site's performance is not, or at least should not be affected by the licensing callbacks.
2) I understand it may be alarming that there are multiple connections, this is standard in HTTPS communication, and from the number im seeing there should be no adverse affect on your server unless you have very little IP transit (unlikely).

I have checked your site, and it seems to be running perfectly well as far as I can tell, however I completely appreciate this may not be the experience you're having, if this is the case, please get in touch directly to me on James -at- InstantASP.co.uk and I will look into this further with you.

We are aware of some issues with the licensing system, this however is not (currently) one of them, we do have planned several improvements to the way the licensing system works, the first of which is a hardware and infrastructure improvement we are currently undertaking, which should be available/online within the next 10 days or so.

As I say, if you have further enquiry directly related to your site and are not getting a response, then please do email myself directly.


Kindest Regards,

James Trott

Hi All,

Hope your very well.

I'm sorry to hear this. I've just sent a license file to your email which should resolve this problem.

By default we do use a web service on our servers  to validate single web site licenses. The results from the web service are cached locally on your web server and you should only see your server talk to our server every 48 hours or when the ASP.NET cache is cleared. 

The license file i've just sent you is a file based license and will skip the web service call. We do also provide file based licenses upon request typically for customers behind firewall's without access to the public internet. I've sent a file based license to your email address to ensure your installation wilt not attempt to talk to our web service.

I do agree with James on this and i would be very surprised if it was the web service call resulting in poor performance. The web service simply returns a boolean and this value is cached locally on your own web server. If our site is unavailable the web service will simply skip the check and the product will continue to work as expected. It will then check again every 48 hours to see if our licensing server is back online. If for any reason our licensing server is down the forum will just continue to work.

I really only have two suggestions without knowing a little more about your server confirmation...

1. Do you have more than one processor in your web server? If so this could be related to the workstation / server garbage collection issue. Are you noticing the aspnet_wp process taking up much memory? If you have more than one processor try the following in your machine.config...

<configuration>
 <runtime>
   <gcServer enabled="true" />
 </runtime>
</configuration>

You can read a little more about this at http://support.instantasp.co.uk/FindPost11443.aspx

2. Are your database indexes fragmented? Fragmentation should not be more than around 10% for any index. You can use DBCC SHOWCONTIG for SQL Server 2000 or the options within Management Studio for 2005 to check index fragmentation. IF you would like more information on this don't hesitate to respond.

If you can provide any further information on the specific performance problems your both experiencing i'll certainly try to help further. If the option is available i'll remote into your server to take a look first hand.

Jay you mention you had an issue we didn't help with? I recall helping with the forthcoming events issues and we'll be looking at improving this with v4.2. If you want to send me a quick email on ryan@instantasp.co.uk if your having any further problems i'd be delighted to help, 

Looking forward to your response and assisting further,


Kindest Regards,

Ryan Healey

Hey guys,

Thanks for the response. At the time of my post I was frustrated as you can tell, as I'd spent a long while trying to isolate any problems with our server/network/applications. Nothing abnormal was afoot so I presumed there was a link between this sites troubles and ours. Clearly this isn't conclusive, but a fair assumption to make I think. Thank-you for being diplomatic, given our mood...

As of this afternoon we've had no further problems, everything is back to it's usual speed, perhaps even a little faster if I'm not mistaken. I'll have a look tonight at your other recommendations Ryan, thanks! One thing I can say though is that we don't have multi-processor servers, unfortunately

I completely understand about the licensing call-backs, and expected them to be asyncronous. Thank-you for the file, I haven't got it yet (jay at londonbikers.com) though appreciate the thought.

Keep up the good work...

Just as an aside, Multi-Core CPU's with the OS optimised to use both cores, or any kind of VPS system which runs with a single CPU from multi-CPU hardware, may have simmilar effects, although this would be heavily configuration dependant, hyper-threading would cause it too, but to a much lesser extent (again though, that would depend on the configuration, by default you shouldnt notice).

We noticed a slow-down today as well, which was disheartening, I was hoping the issue had been resolved.

What's this license file I hear of? I've not received one. I would like to give it a go!

Not had time to look at the other points, but should do tonight. Too damned busy
